Abstract:
1. An offset modulation-orthogonal frequency division multiplexing (OM-OFDM) transmission method with cyclic prefix, wherein the transmission method includes a method for generating transmitted signals and a method for processing received signals, wherein, the method for generating transmitted signals includes the following steps: a. performing channel encoding and symbol mapping for the transmitted information bits, to obtain digital baseband modulation symbols with real values; b. dividing the digital baseband modulation symbols into K streams, wherein, K is a positive integer; c. performing serial/parallel conversion in length 2N d. performing cyclic convolution for the transmitted symbols in each stream with the coefficient of time domain pulse shaping filter for the stream, and modulating the result in offset quadrature amplitude modulation (OQAM) mode to the frequency band corresponding to the stream, to obtain the digital baseband signals in the stream; e. combining the digital baseband signals on all streams by summing, to obtain the transmitted signals, to which a cyclic prefix will be inserted later; f. inserting a cyclic prefix, to obtain digital baseband transmitted signals; and wherein, the method for processing received signals includes the following steps: g. removing the cyclic prefix from the received signals; h. performing band-pass filtering for the received signals for each stream, and performing combined equalization for multi-streams, perform demodulation and decoding.
