基于结构化压缩感知的NOMA系统多用户检测
NOMA system's multi-user detection based on structurization compressed sensing
摘要
Abstract
Since the demands of the future 5G mobile communication is hugely increased in the aspects of spectrum effi-ciency and user connection quantity,the non-orthogonal multiple access(NOMA)technology as a key technology of 5G attracts the widespread attention because of its outstanding advantage. The scheduling-free NOMA system can shorten the transmission delay and save the signaling overheads,but the user activity should be detected in the receiving end. According to the theory of structurization compressed sensing,the impact of active users and overloading rate on the system detection performance while the multi-user detection is carried out in NOMA system is analyzed emphatically. The results show that,with the increase of the number of active users and overload rate,the detection performance of the commonly-used compressed sensing detection algo-rithm becomes worse,but the detection performance of the structured iterative support detection(SISD)algorithm is still better.关键词
