QRMMLD算法主程序 仿真 应用 需要主程序调用 请自行解决-Motivated by the need for high throughput sphere decoding formultipleinput-

multiple-output (MIMO) communication systems, we propose

a parallel depth-first sphere decoding (PDSD) algorithm that provides

the advantages of both parallel processing and rapid search

space reduction. The PDSD algorithm is designed for efficient implementation

on programmable multi-processor platforms. We investigate

the trade-off between the throughput and computation overhead

when the number of processing elements is 2, 4 and 8, for a 4×

4 16-QAM system across a wide range of SNR conditions. Through

simulation, we show that PDSD can offer significant throughput improvement

without incurring substantial computation overhead by

selecting the appropriate number of processing elements according

to specific SNR conditions.
