Abstract

The embodiment of the invention provides a sequence processing method and equipment. The sequence processing method comprises the following steps: performing channel encoding processing on a first bit sequence through a transmitting terminal, thereby obtaining a second bit sequence; performing interleaving processing on the second bit sequence through the transmitting terminal, thereby obtaining a third bit sequence, wherein the third bit sequence comprises a bit 0 or a bit 1; acquiring a partitioning ratio through the transmitting terminal according to a modulation mode; processing the third bit sequence through the transmitting terminal according to the partitioning ratio, thereby obtaining a fourth bit sequence, wherein the fourth bit sequence comprises a bit 0 or a bit 1, and the ratios of the bit 0 and the bit 1 in the fourth bit sequence are different from those of the bit 0 and the bit 1 in the third bit sequence; performing modulation processing on the fourth bit sequence through the transmitting terminal; transmitting a bit sequence obtained through modulation processing to a receiving terminal from the transmitting terminal. By adopting the technical scheme of the embodiment of the invention, the channel capacity of a wireless communication system can be improved.

Description

【Technical field】 [0001] The present invention relates to signal processing technology, in particular to a sequence processing method and equipment. 【Background technique】 [0002] In the prior art, in a bit sequence transmission system, such as a two-way relay system based on physical layer network coding, a first sending device and a second sending device can simultaneously send a bit sequence to a receiving device (such as a relay node). Taking the first sending device as an example, the first sending device first performs low density parity check code (Low Density Parity Check Code, LDPC) channel coding processing on the input bit sequence, then performs interleaving processing on the bit sequence, and finally performs the bit sequence Modulation processing is performed and sent to the receiving device through a noise channel. When the bit sequence is modulated, the bit sequence is mapped to the constellation diagram corresponding to the modulation mode of the modulator ...
