Abstract

The invention provides a transmitting method for multiple access. The transmitting method comprises the following steps: a transmitter performs channel encoding on a bit sequence so as to determine an encoded sequence; performing symbol modulation on the encoded sequence; performing grid mapping on the modulated symbol sequence so as to determine a mapped sequence, and sending the mapped sequence. The invention further provides a multiple access method which comprises the following steps: a receiver receives a mixed signal from multiple transmitters, wherein the mixed signal is the signal obtained after performing grid mapping processing on the data or the signal obtained after performing the interleaving processing and the grid mapping processing on the data by each transmitter; the mixed signal is decoded according to the grid mapped pattern information corresponding to each transmitter or the corresponding interleaved pattern information or scrambling signal and grid mapped pattern information so as to obtain the data from each transmitter. The data from different transmitters is decoded by use of the interleaved pattern information or the scrambling information and/or the grid mapped pattern different from one another, thereby distinguishing multiple transmitters.

Description

Technical field [0001] The present invention relates to the field of mobile communication. Specifically, the present invention relates to a multiple access method, a transmission method for multiple access, a transmitter and a receiver for multiple access. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and IoT (Internet of Things), it will bring unprecedented challenges to the future mobile communication technology. For example, according to the International Telecommunication Union ITU report ITU-R M.[IMT.BEYOND 2020.TRAFFIC], it can be predicted that by 2020, the growth of mobile traffic will increase by nearly 1,000 times compared with 2010, that is, in the 4G era. , User equipment) connections will also exceed 17 billion. As a large number of IoT devices gradually penetrate into mobile communication networks, the number of connected devices will be even more alarming. In order to co...
