Background technology
Diversity receiving technology is that moving communicating field is used a kind of very widely anti-fading technology, and its basic thought is: if chosen two or more independently samplings of one road signal, the decline of these samples is incoherent.It is much smaller to this means that any one sample of likelihood ratio that all samples are lower than a preset level simultaneously is lower than the probability of this value.Thereby it is more light than the fade-out of any one single sample suitably to merge the signal that forms by different samples.That is to say that diversity receiving technology is to utilize the appropriate combination of a plurality of signals that receive to reach raising communication quality and systematic function.In the relatively poor adverse circumstances of signal quality, can effectively reduce the influence of decline by adopting receive diversity, improve the receptivity of portable terminal.Yet, under the good environment of signal quality, diversity reception to the terminal receptivity to improve effect limited.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Embodiments of the invention aim to provide a kind of signal diversifying method of reseptance and diversity reception terminal, can effectively reduce the work power consumption of receiving system.
The signal diversifying method of reseptance that the embodiment of the invention provides, the flow chart that shows as described in Figure 1 comprises the following steps:
S11, received signal detects the quality metrics value that indicates described signal quality;
S12, described quality metrics value and preset threshold value are compared, when described quality metrics value during greater than described default pass diversity threshold value, adopt the receiving mode of no diversity reception, when described quality metrics value less than described default when opening the diversity threshold value, adopt the receiving mode that has diversity reception.
The signal diversifying method of reseptance that the embodiment of the invention provides, made full use of the advantage of diversity receiving technology, according to quality evaluation to received signal, receive mode is disposed dynamically, both guaranteed the performance of system, also effectively reduce the work power consumption of system, improved the temperature rise situation of system simultaneously, reduced the heat radiation risk of system.And make under the battery-powered situation in system, the reduction of work power consumption will increase the operating time of battery, promptly increase the operating time of system.
Wherein, the quality metric value detection sign that indicates described signal quality can be indicated (CQI for channel quality, Channel Quality Indication), received signal code power (RSCP, Received Signal Code Power) and received signal strength indicator value parameters such as (RSSI, ReceivedSignal Strength Indication).Usually, the above-mentioned parameter of high value represents that a channel has high quality, and promptly the current demand signal quality is better, otherwise low value then representation signal is second-rate.Embodiments of the invention can adopt a kind of parameter as the quality metrics value, the combination that also can use multiple parameter is simultaneously as the common marking signal quality of quality metrics value, can select at least a parameter value quality metrics value of signal quality as a token of according to actual conditions.
It is pointed out that described pass diversity threshold value and to open the diversity threshold value identical or different, promptly described pass diversity threshold value with open the diversity threshold value can be identical, also can be different.At this moment because the quality of signal quality is a relative notion, and there is different performance requirements in different systems, the Push And Release of diversity reception also is different to the Effect on Performance degree under different situations.May occur, when the quality metrics value is in certain numerical value interval, the Push And Release of diversity reception is to the not significantly influence of receptivity of system, in this case, the previous status of maintenance system gets final product, need not carry out the Push And Release of diversity reception, therefore can make the actual conditions according to this system different pass diversity threshold values is set and open the diversity threshold value, the quality metrics value in the numerical value interval between two threshold values represents that promptly the Push And Release of diversity reception can not have obviously influence to system of system.Can the size of closing the diversity threshold value and opening the diversity threshold value be set according to actual conditions.
In addition, because signal fluctuation, relatively judgement signal quality by a quality metrics value and predetermined threshold value is inaccurate often, and, if the quality metrics value of the detection signal that does not stop opens and closes diversity reception continually according to judged result, can have a strong impact on the performance of system, therefore in the S11 step, can be in each specific time cycle every the quality metrics value of the described signal quality of particular time interval continuous detecting sign N time, N is more than or equal to 1.Wherein, each representative of specific time cycle is every through certain hour, and the detection signal quality once avoids opening and closing continually diversity reception; To the detection of signal quality, signal quality is judged at every turn, can be improved the accuracy of judged result like this, the misoperation of avoiding signal fluctuation to cause by gathering N quality metrics value.
Specify the signal diversifying method of reseptance that the embodiment of the invention provides below, as shown in Figure 2, comprising:
S21, received signal, in the specific time cycle every the CQI value of the described signal quality of particular time interval continuous detecting sign N time;
In the present embodiment, with the CQI value quality metrics value of described signal quality as a token of.The CQI value is the measurement standard of the communication quality of wireless channel, and usually, the CQI of a high value represents that a channel has high quality, and promptly the current demand signal quality is better, otherwise the CQI value is lower, and then representation signal is second-rate.
Since signal fluctuation, if judge that by a CQI value signal quality may be inaccurate, the therefore misoperation that causes for fear of signal fluctuation, in this step, continuous detecting CQI value N time.In addition, frequent opening/closing diversity reception can influence the performance of system, and therefore, present embodiment regularly detects signal quality, detects the signal quality in this period in a described specific time cycle.It is pointed out that the time cycle described in this step, the time interval and N value, according to actual conditions and system requirements setting.
Here attention is, in the present embodiment, indicates that the quality metrics value of described signal quality is not limited to the CQI value, can also judge signal quality by RSCP and RSSI etc., and can also be that the combination of multiple parameter is judged signal quality.When the combination of adopting one or more parameters during as the signal quality metrics value, the workflow of the diversity receiving method that the embodiment of the invention provides is identical as the flow process of signal quality metrics value with present embodiment employing CQI.
S22 with default pass diversity threshold, judges whether N the CQI value of obtaining all is higher than described pass diversity threshold value;
Because the quality of signal quality is a relative notion, there is different performance requirements in different systems, the Push And Release of diversity reception also is different to the Effect on Performance degree, therefore the size that need described pass diversity threshold value be set according to the performance and the job requirement of actual conditions and system.When CQI value during greater than described pass diversity threshold value, represent the signal quality that receives this moment good, the CQI value is during less than described pass diversity threshold value, and representation signal is fair or relatively poor.If N the CQI value of obtaining in the S21 step all is higher than described pass diversity threshold value, i.e. the inferior described pass diversity threshold value that is higher than of CQI value N continuous, this illustrates that the signal quality of current period is good.
S23 when described N CQI value all is higher than described pass diversity threshold value, judges whether diversity reception is in closed condition;
S24 if diversity reception before is in running order, then closes diversity reception;
S25 if diversity reception before is in closed condition, then maintains the original state;
Described N CQI value all be higher than described pass diversity threshold value, be that the signal quality that receives the current period is good, therefore, diversity reception to receptivity to improve effect limited, adopt the receiving mode of no diversity reception this moment.
Further, present embodiment also comprises:
S26 when described N CQI value all is not higher than described pass diversity threshold value, with the default diversity threshold of opening, judges whether N the CQI value of obtaining all is lower than the described diversity threshold value of opening;
When described N CQI value all was not higher than described pass diversity threshold value, it may partly be higher than described pass diversity threshold value, and part is lower than described pass diversity threshold, partly or entirely equals described pass diversity threshold value, perhaps all is lower than described pass diversity threshold value.This situation may be that reasons such as signal fluctuation cause, therefore, if only with the judged result of S22 step, when described N CQI value all is not higher than described pass diversity threshold value, just think that signal quality is relatively poor at this moment, it is coarse needing to adopt the receiving mode that has diversity reception, might cause misoperation, therefore also comprised this step in the present embodiment, judged whether described N CQI value all is lower than the described diversity threshold value of opening; Like this, just can reduce the probability of misoperation, can also avoid frequent opening/closing diversity reception, guarantee systematic function.
Because the quality of signal quality is a relative notion, there is different performance requirements in different systems, the Push And Release of diversity reception also is different to the Effect on Performance degree, therefore need the described size of opening the diversity threshold value be set according to the performance and the job requirement of actual conditions and system.When the CQI value less than described when opening the diversity threshold value, representation signal is of poor quality.Therefore, if N CQI value obtaining all is lower than the described diversity threshold value of opening in the S21 step, promptly CQI value N continuous is inferior is lower than the described diversity threshold value of opening, and this illustrates, the poor signal quality of current period reception.It is pointed out that the pass diversity threshold value described in the present embodiment and open the diversity threshold value and can be identical value, also can be different values, can be according to the actual conditions setting.
S27 when described N CQI value all is lower than describedly when opening the diversity threshold value, judges whether diversity reception is in closed condition;
S28 if diversity reception before is in closed condition, then opens diversity reception;
S29, if described N CQI value all be not lower than described open the diversity threshold value or, diversity reception before is in running order, then maintains the original state.
Because described N CQI value all be lower than the described diversity threshold value of opening, i.e. the poor signal quality of current period, diversity reception can effectively reduce the influence of decline, improves the receptivity of system, and therefore employing at this moment has the receiving mode of diversity reception.
In sum, the diversity receiving method that the embodiment of the invention provides according to quality evaluation to received signal, disposes dynamically to receive mode, when signal quality is good, adopt the receiving mode of no diversity, when signal quality is relatively poor, adopt the receiving mode that has diversity, so both guaranteed the performance of system, also effectively reduce the work power consumption of system, improved the temperature rise situation of system simultaneously, reduced the heat radiation risk of system.And make under the battery-powered situation in system, the reduction of work power consumption will increase the operating time of battery, promptly increase the operating time of system.
