摘要
LTE代表长期演进(Long Term Evolution)，现在是一种公认的协议，旨在支持各种高数据速率应用，特别是包含当前和多媒体功能。它依靠OFDMA和MIMO能力的融合，在频率选择信道(ISI)中提供高速率，从而有效地对抗码间干扰。该协议在各种信道上的性能已经被研究过，但是没有研究报告在Nakagami信道上存在这样的问题。在Nakagami-m衰落信道中，采用SISO、发射分集和开环空间复用(OLSM)三种不同的传输模式，对BLER性能和可实现吞吐量进行了评价。使用最小二乘法估计OFDM信道，并在接收端采用最近提出的K最佳软球解码器(KBSSD)。此外，本文还报告了重传次数对BLER性能的影响。
Performance study of Nakagami-m fading channel in LTE system
LTE which stands for Long Term Evolution is now an agreed-upon protocol that aims at supporting various high data rate applications particularly encompassing current and multimedia features. It relies on the merging of OFDMA and MIMO abilities for affording high rates in frequency selective channels (ISI), thus efficiently combating inter-symbol interference. The performance of this protocol has been studied for various channels, however, no study reports such an issue for Nakagami channel. In this paper, the BLER performance and the achievable throughput are evaluated in Nakagami-m fading channel with 3 different transmission modes, namely, SISO, transmit diversity and open loop spatial multiplexing (OLSM). The OFDM channel is estimated using the least square approach and the very recently proposed K Best-Soft Sphere Decoder (KBSSD) is adopted at the receiver side. Also, the impact of the number of retransmissions on the BLER performance is reported herein.
