Please refer to Fig. 9, (for example: the EDGE) schematic diagram of wireless telecommunication system show existing hybrid modulation.Existing in order between being controlled at tiltedly the performance number in district 900 in the mode of linear pointwise performance number is increased to B.As shown in Figure 9, existing is directly to connect performance number A and performance number B to form a linear power line segment in an oblique district 900.Yet, adopt the existing method shown in Figure 11 A-11B, will in an oblique district 900, produce transient current.
Figure 11 A-11B illustrate the high power transient current for existing hybrid modulation wireless telecommunication system in a tiltedly influence of the power output in district, be presented at different frequency under respectively and transient current 1100 that different time descends to be taken place.Shown in Figure 11 A, in an oblique district 900, transition indication 1100a-b surpasses timing protection 1110a-b (dotted line).If transition indication 1100a-b surpasses timing protection 1110a-b, may (for example: mobile phone) adjacent channel of Shi Yonging will noisy situation generation by other device for mobile communication.In addition, shown in Figure 11 B, it is that the transient current peak 1100 of 0.4MHz produces from transmitting channel that a frequency is arranged in oblique district 900.Figure 11 B shows the power of representing with frequency function.Therefore can determine to take place the part of high transient current 1100 at an oblique line (for example in an oblique district 900).Shown in Figure 11 B, the performance number on transient current peak has exceeded general tolerance limit degree greater than 20dBm.
In order to solve the issuable problem of above-mentioned transient current, the invention provides a kind of method and device that forms notching curve in an oblique district, (for example: the maximum that timing/power protects) surpass a preset maximum value so that an immediate current power of tiltedly distinguishing is neither.For instance, in one embodiment, the present invention relevant for reduce in the communications protocol between the oblique method of the immediate current in district, comprise the following steps:
Based on the decision of recessed power curve at the oblique output power value (for example :) in district at all time points, make oblique some performance number in district be lower than be next between tiltedly first time slot before the district and/or be next between the performance number of signal of second time slot after tiltedly distinguishing.Power curve is not the straight line as skew curve between Fig. 9 existing, though also may comprise one or more parts that are essentially linear segments.
2. configuration or produce notching curve makes minimum point (for example: the lowest power value) occur in transient electrical in fact and fail to be convened for lack of a quorum and part takes place and be lower than a critical value (a for example default performance number).In general, the central authorities that tiltedly distinguish between the minimum point of notching curve occurs in.
3. use at least one primitive curve to produce notching curve.In one embodiment, notching curve comprises primitive curve FL (t) and FR (t).
Figure 12 shows according to the high power transient current of a preferred embodiment of the present invention for the hybrid modulation wireless telecommunication system in a tiltedly influence of the power output in district, shows the output power curve figure that represents with the function of time.Between being next to tiltedly before the district 900, output power curve 1240 has at time slot 1 and one is about-first performance number (using the 8PSK modulation) of 6dBm.Between being next to tiltedly after the district 900, output power curve 1240 has second performance number (using the GMSK modulation) that is about 0dBm at time slot 2.Yet in oblique district 900, it is recessed that output power curve 1240 is usually, and have first (or left side) and increase section 1222, second (or right) and increase section 1224 and be about-minimal power values of 30dBm.At some specific embodiment, between power curve 1240 tiltedly the critical value of the minimum point 1223 in district 900 can be set at-6dBm ,-10dBm or-20dBm, or even more be lower than be next between oblique both juniors of first and second performance number before or after the district 1220.Suppose critical value be as shown in figure 12-20dBm, minimum point (minimal power values 1225) is apparently less than this critical value.
Figure 13 A-13B shows the power output-output frequency function and the power output-function of time under specific output frequency according to a preferred embodiment of the present invention respectively, and then shows the result by the present invention produced.It is first output power curve of function that Figure 13 A shows with the frequency, and (setting transient current herein and be δ=0.4MHz) is second output power curve of function with time and Figure 13 B is presented under the given frequency.On first output power curve, the performance number of transient current 1360a-b respectively the position+/-0.4MHz and being lower than apparently by protection 1110a-b defined performance number.Therefore, shown in Figure 13 A-13B, have a lower peak (its performance number is lower than 20dBm) at an output power curve in oblique district 900, this is compared to the peak of the existing system shown in Figure 11 B (its performance number is higher than 20dBm).By this, can reduce or avoid any interference to occur in the transient current of the higher-wattage that adjacent channel causes.
Figure 14 shows the calcspar of using mobile unit of the present invention.As shown in figure 14, except above-mentioned output control device 800, controller 839, and power amplifier 831, mobile unit 83 also has estimator 87 during a wireless control module 85 and the transition.Estimator 87 or controller 839 can be all or separately be implemented on a microprocessor or in one or more devices of a physical layer (for example: integrated circuit) between wireless control module 85, output control device 800, transient period.It should be noted that, controller 839 can (1) be adjusted the power output of power amplifier according to output power curve, and the switching that also can (2) be controlled at the performance number/modulation type between adjacent time slot (for example: second modulation type that switches to second time slot from first modulation type of first time slot).In order to control the switching of modulation type, controller 839 can also comprise general objects output (GPO) device or three-way command unit.
At the TDMA communication system, wireless control module 85 81 receives signals and exports a controlling signal (for example: at the CONTROL of Figure 14) to output control device 800 from the base station.Controlling signal is included in some or all characteristic of each time slot of subsequent data frame.Characteristic can be included in the performance number, each time slot (therefrom can point out, determine or be provided with between adjacent time slot between oblique district) of each time slot of Frame the position, with and/or the modulation type of each time slot of Frame.
For instance, controlling signal notice power device 800 originally the time slot 1 power demand value of Figure 12 should be A (be about-6dBm) and time slot 2 power demand values should be B (being about 0dBm).So 900 output power curve is tiltedly distinguished in output control device 800 configurations or generation between between time slot 1 and time slot 2.And at least one output power value of output power curve is in fact less than performance number A and B.After output power curve produced, estimator 87 was also estimated and/or determine in the output power curve that central all power outputs are less than a preset critical between the transient period of (and tiltedly distinguish 900) between transient period.At some specific embodiment, be included between transient period output power curve during minimum point took place or the time.Therefore, between the transient period of output power curve, controller 839 switches to performance number B (and/or can switch to second modulation type from first modulation type) with the control output power value of power amplifier 831 and from performance number A.
Therefore, except the performance number conversion between the control time slot, at the EDGE communication system, mobile unit 83 also can be used to control the modulation type conversion between time slot.For example, can to notify output control device 800 be that 8PSK and time slot 2 required modulation types are GMSK at the time slot 1 required modulation type of Figure 12 to controlling signal.So 900 output power curve is tiltedly distinguished in output control device 800 configurations or generation between between time slot 1 and time slot 2.After output power curve produced, estimator 87 was also estimated and/or determine in the output power curve that wherein all power outputs are less than a preset critical between the transient period of (and tiltedly distinguish 900) between transient period.At some specific embodiment, be included between transient period output power curve during minimum point took place or the time.Therefore, between the transient period of output power curve, controller 839 can switch to GMSK modulation type (time slot 2) from 8PSK modulation type (time slot 1) with power amplifier 831.
Therefore, by the performance number/modulation type that switches between transient period, this performance number/modulation type switches the transient current that produces to be taken place between transient period, and can be controlled by the method and the device of above-mentioned reduction power of the present invention.As shown in figure 13, the output power value that is meant of transient current increases suddenly and reduces forming a peak, and has suitable high power value.In the present invention, because the output power value between transient period can or be lower than a critical value for the lowest power value, therefore, no matter any unexpected increase, the performance number on the peak that is produced by transient current is may command and will can not surpass the timing protection all.
In sum; though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; those skilled in the art can be used for a variety of modifications and variations under the premise without departing from the spirit and scope of the present invention, so protection scope of the present invention is as the criterion with claim of the present invention.
