The present invention provides a method for receiving and processing M-ary orthogonal modulation and M-ary channel coding signals. The method for receiving and processing M-ary quadrature modulation and M-ary channel coding signals includes: generating M pieces of matched filter value information, wherein, among the M pieces of matched filter value information, a matched filter value corresponding to a matched filter value that meets a preset condition. The waveform serial number of the quadrature signal is used as the data demodulation information of the received M-ary quadrature modulation signal; the data demodulation confidence level vector is generated according to the M pieces of matched filter value information, wherein one data demodulation confidence level corresponds to one matched filter correlation value information ; Perform channel decoding according to the data demodulation information and the data demodulation confidence vector, thereby obtaining the decoded transmission data. The method for receiving and processing M-ary orthogonal modulation and M-ary channel coding signals of the present invention combines M-ary quadrature modulation and M-ary channel coding, thereby effectively improving the transmission performance of a multi-ary quadrature modulation system.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method for receiving and processing M-ary quadrature modulation and M-ary channel coding signals and a device for receiving and processing M-ary quadrature modulation and M-ary channel coding signals. Background technique [0002] The multi-ary system quadrature modulation signal mode has been widely used in the field of contemporary communication and navigation because of its high data transmission efficiency. For example, the Japanese quasi-zenith satellite navigation system (QZSS) adopts the 256-ary CSK quadrature modulation signal method in the L6 signal broadcast (reference [IS-QZSS-L6-001]), which can provide much higher than other Satellite navigation system data dissemination rate. [0003] In recent years, with the rapid development of channel coding technology, many advanced channel coding methods close to Shannon's limit have been proposed, such as Tu...
