【电信学】【2007.05】【含源码】符号波长间隔天线MIMO系统的FPGA实现

本文为加拿大新不伦瑞克大学（作者：Harshal Desai）的硕士论文，共91页。

对于视距（LOS）无线信道，最近的研究表明，为了有效地提高多输入多输出（MIMO）系统的性能，接收机的天线单元必须以符号波长（[光速]/[符号速率]）的尺度进行分离。本文的主要工作是设计、实现并测试基于这种分离关系的二乘二（2x2）系统，该系统在单块现场可编程门阵列（FPGA）板上实现。系统中的自适应空时（ST）接收机采用一种最小均方（LMS）算法来适应这些系数。该系统采用Altera Quartus II软件开发，使用Verilog HDL作为编程语言。利用MATLAB和Altera SignalTap II逻辑分析仪软件对系统进行了调试和收敛性测试。结果表明，该系统成功收敛，系统的收敛系数趋于选定的零值或较小值范围。

For Line-of-Sight (LOS) radio channels, recent research shows that in order to improve effectively the performance of a Multi-input Multi-output (MIMO) system, the antenna elements at the receiver must be separated on the scale of a symbol wavelength ([speed of light]/[symbol rate]). The main focus of this thesis was to design, implement and test a two-by-two (2X2) system based on that separation. The system was implemented on a single Field Programmable Gate Array (FPGA) board. The adaptive Space-Time (ST) receiver in the system includes a Least Mean Square (LMS) algorithm to adapt the coefficients. The system was developed using Altera Quartus II software and Verilog HDL was used as the coding language. The system was debugged and tested for convergence using MATLAB and the Altera SignalTap II Logic Analyzer software. The results indicate that the system converges successfully. The system’s converged coefficients show selected ranges of zeros or small values.
