Abstract
The invention discloses a wireless transmitter circuit which comprises a to-be-transmitted data length detecting circuit, a transmitting power control circuit and a wireless data transmitting circuit. The to-be-transmitted data length detecting circuit is used for detecting the length of data to be transmitted, and the transmitting power control circuit is connected with the to-be-transmitted data length detecting circuit and controls the transmitting power according to the detected to-be-transmitted data length. The larger the to-be-transmitted data length is, the higher the transmitting power is; otherwise, the smaller the to-be-transmitted data length is, the lower the transmitting power is. The wireless data transmitting circuit is connected with the transmitting power control circuit and transmits data in a wireless mode under the control of power control signals output by the transmitting power control circuit. According to the wireless transmitter circuit, the transmitting power can be adjusted according to the length of the data to be transmitted, and the probability that a receiver receives the date accurately is increased.
Description
Technical field
The present invention relates to a kind of radio transmitters circuit.
Background technology
Wireless communication system can be subject to the various interference on wireless channel when communicating and cause the data of transmission can not be received device normally to receive.In order to ensure reliable transfer of data, general radio communication all can have retransmission mechanism, namely after transmitter sends data, if receiver can normally receive, so just returns transmitter handshake; Like this, when transmitter is after sending data a period of time, also do not receive the handshake of receiver, so just think that receiver does not receive transmission data, resend original data.There is two problems in such process, and the first, if the interference in communication channel does not disappear, even if so retransmit, receiver is also again not receive.The second, even if receiver have received, but send one group of data, transmitter have sent 2 times, sends energy, and the time of communication cost is all under normal circumstances 2 times.In addition, when sending data and being longer, it is larger that it causes receiver to receive wrong possibility by the interference in channel.And increase transmitted power, the impact of interference on signal can be reduced, thus receiver can correctly be received.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of radio transmitters circuit, according to the length adjustment transmitted power sending data, can increase the probability that receiver correctly receives data.
For solving the problems of the technologies described above, radio transmitters circuit of the present invention, comprising:
One detects data length circuit to be sent, for detecting the length of data to be sent;
One transmitting power control circuit, is connected with described detection data length circuit to be sent, according to the data length to be sent detected, controls transmitted power; When data length to be sent is longer, its transmitting power is larger; Otherwise, when data length to be sent more in short-term, its transmitting power is less;
One wireless data transtation mission circuit, is connected with described transmitting power control circuit, under the control of the power control signal exported at described transmitting power control circuit, adopts wireless mode to send data.
Adopt radio transmitters circuit of the present invention, data length to be sent is directly proportional to transmitting power, can increase long data like this and be received the possibility that device correctly receives, thus reach minimizing sending times, reduces time and the energy of communication cost on the whole.
Radio transmitters circuit of the present invention is applicable to wireless communication system needs external power supply, and system needs the field of province's power consumption.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the present invention is further detailed explanation:
Accompanying drawing is the structured flowchart of radio transmitters circuit one embodiment.
Embodiment
Shown in accompanying drawing, here is an embodiment, and described radio transmitters circuit, comprising: one detects data length circuit to be sent, a transmitting power control circuit, a wireless data transtation mission circuit.
Because the radio communication interference be subject on wireless channel causes reception mistake, and it is longer to send data, it is larger that it causes receiver to receive wrong possibility by the interference in channel, and increase transmitted power, the impact of interference on signal can be reduced, thus receiver can correctly be received.So described radio transmitters circuit detects the length of data to be sent by a testing circuit, then control a transmitting power control circuit by the length of data to be sent.When sending data length and being longer, transmitted power is larger, otherwise when sending data length more in short-term, transmitted power is less.
Detect two inputs of data length circuit to be sent in accompanying drawing, send data length signalization and address pointer, multi-form according to two kinds of radio transmitters transmission data, get one of them.
Two kinds of modes can be had because radio transmitters sends data:
The first, transmission data is all stored in the internal buffer of wireless data transtation mission circuit, and then sends one by one, and internal buffer generally has an address pointer to show the data amount check in buffer memory.
The second, by external interface, writes data in batch in process of transmitting, is sent by wireless data transtation mission circuit simultaneously.
Like this, corresponding described detection data length circuit to be sent, just has two kinds of modes detecting data length to be sent; The first is the length obtaining data to be sent according to the address pointer of the internal buffer of described wireless data transtation mission circuit; The second is the length directly being arranged data to be sent by external interface, namely arranging by sending data length signalization the register detected in data length circuit to be sent by external interface, obtaining data length to be sent.
Above by embodiment to invention has been detailed description, but these are not construed as limiting the invention.Without departing from the principles of the present invention, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection scope of the present invention.
