The present disclosure relates to a communication method and
system for converging a 5th-Generation (5G) communication
system for supporting higher data rates beyond a 4th-Generation (4G)
system with a technology for
Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building,
smart city,
smart car, connected car, health care,
digital education, smart retail, security and safety services. Embodiments of the present invention provide a multiple
access method, a multiple access
transmitter and a multiple access
receiver. The multiple
access method comprises the steps of: performing, by a
transmitter, channel coding on a bit sequence to determine a coded sequence;
interleaving and / or scrambling the coded sequence, and performing multidimensional
constellation modulation on the interleaved and / or scrambled sequence; performing
grid mapping on the modulated symbol sequence to determine a mapped sequence, and transmitting the mapped sequence; receiving, by a
receiver, mixed signals from multiple transmitters, the mixed signals are obtained by performing, by each of the multiple transmitters,
interleaving and / or scrambling, multidimensional
constellation modulation and
grid mapping on data; and, decoding, by the
receiver, mixed information according to interleaver information and / or scrambler information, multidimensional
constellation information and
grid mapping pattern information corresponding to each
transmitter to obtain data corresponding to each transmitter.
