The invention provides a signal sending and processing method. A transmitter generates and sends a data frame, the data frame comprises a signal detection sequence, a leading sequence and a data sequence for indicating the data frame, a receiver sequentially detects whether a received signal contains the signal detection sequence at a preset code rate, if yes, the receiver processes the received signal, as a code rate of the signal detection sequence is smaller than a code rate of the leading sequence, the code rate of the receiver detecting the signal detection sequence can be smaller than the code rate of the leading sequence, so the receiver can firstly utilize a relatively low code rate to detect whether the data frame exists, if the data frame exists, processing is carried out, for multiple transmission channels, the relatively low code rate can be firstly utilized to detect whether the transmission channels have the data frame. Compared with a mode of employing relatively high frequency to detect each transmission channel in the prior art, power consumption of the receiver can be reduced.
Description
technical field [0001] The present application relates to the field of communications, and in particular to a signal sending and processing method, a transmitter, and a receiver. Background technique [0002] In the multi-channel communication service, the transmitting end randomly selects a transmission channel from multiple transmission channels for transmitting signals, and does not inform the receiving end which transmission channel is used in advance. When receiving a signal, the receiving end usually filters each transmission channel to obtain the baseband signal of each transmission channel, and then determines which channel has signal transmission through sampling and detection. [0003] For example, if figure 1 As shown, the communication system uses the 0-15MHz frequency band to transmit signals, divides the 0-15MHz frequency band into 15 channels, each channel occupies 1MHz, and the baud rate of signal transmission is 30MHz (that is, the data transmission rate). ...
