使用SNR（信噪比）进化算法评估了准环境低密度奇偶校验检查（QC-LDPC）编码的部分访问多访问多访问（IDMA）系统的性能。部分访问IDMA系统是IDMA系统，其中0s（即非能量传输）插入芯片序列中。 SNR进化算法是开发和采用用于评估系统的。数值和仿真结果表明，部分访问的BER（位错误率）性能比传统范围的Low EB/N0范围更高，并且带有3GPP NR QC-LDPC代码的IDMA系统具有良好的IDMA系统错误地板性能。
The performance of the quasi-cyclic low-density parity-check (QC-LDPC) coded partial-access interleave division multiple access (IDMA) systems is evaluated with the SNR (signal-to-noise ratio) evolution algorithm. The partial access IDMA system is the IDMA system in which the 0s, i.e., non-energy transmission, are inserted into the chip sequence. The SNR evolution algorithm is developed and employed to evaluate the systems. Numerical and simulation results show that the partial access has better BER (bit error rate) performance than that of the conventional full access in a range of low Eb/N0, and the proposed IDMA system with the 3GPP NR QC-LDPC codes has a good error-floor performance.
