[AI-NN-PRMIMO-IN-WIRELESS-COMMUNICATIONS-

Description: 本文基于MIMO检测中性能和复杂度的矛盾,结合具体的MIMO 检测技术进行深入研究,致力于提供能有效缓解性能和复杂度矛盾冲 突的技术方案。论文首先介绍MIMO系统的基本模型,随后针对球 译码(Sphere Decoding)检测及其相关技术、搜索空间预定义检测器 (Search Space Predetermined Detector,SSPD)算法、并行计算对检 测算法的加速作用以及自动重传机制(Automatic Retransmission reQuest,ARQ)带来的时间分集对复杂度压力的缓解作用等几方面 展开研究。-As far as is known,few literature deals with the quantified relationship between complexity and detection performance of SD. Sphere radius is proposed to be a transition parameter,thus the quantified relationship is analyzed theoretically.This part of work can be divided into three paas:1)In order to analyze the performance of SD,the asymptotic bound of optimal performance is utilized,and latter the performance loss caused by search space reduction is quantified with the help of above bound.Since the performance loss is affected by the sphere radius directly,sphere radius Can be used to represent the performance feature of SD.2)Based on the characteristic of complexity of SD,derive all upper.bound of average complexity;therefore the sphere radius becomes the metric of average complexity.3)By making use of sphere radius,the bridge between performance and complexity can be built.The compute simulations verify above analysis for different MIMO use cases.

[Program docrobust-MIMO-detection

Description: 在多输入多输出系统中的鲁棒球形译码的实现-We present a maximum-likelihood decoding algorithm for an arbitrary lattice code when used over an independent fading channel with perfect channel state information at the receiver. The decoder is based on a bounded distance search among the lattice points falling inside a sphere centered at the receved point. By judicious choice of the decoding radius we show that this decoder can be practically used to decode lattice codes of dimension up to 32 in a fading environement.

[OtherSPHERE-DECODING

Description: :在长期演进(LTE)系统中,球形译码算法拥有接近于最大似然(ML)的误码率(BER)性能。针对在 16QAM和64QAM等高阶调制情况下球形译码算法计算复杂度和所需硬件资源的急剧增加,提出了一种调整符号搜 索策略的改进型球形译码算法。该算法在不同的检测层采用特定的符号搜索方案,并结合一种基于信噪比的动态调 整半径方法。在无线瑞利信道环境下,对各种球形译码算法进行了仿真。仿真结果表明,提出的改进型算法基本保持 传统球形译码算法较低的BER性能,同时还有效地降低了计算复杂度和硬件实现复杂度。-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
