摘要

RRC(根提升余弦)滤波器用于无线通信作为发送和接收滤波器有助于减轻lSI(符号间干扰)。本文分析了不同滚降系数的升根余弦脉冲整形滤波器对一个256子载波的2xl MIMO-OFDM系统的影响。重点研究了实际WiMAX系统中量化位、截断长度和滚转系数的选择。给出了不同滚转系数下的误码率分析。为了评估所提出的设计的性能，在Matlab-Simulink中进行了仿真。

Transmit and receive filter design for MIMO-OFDM based WiMAX systems

RRC (Root Raised Cosine) filters used in wireless communication as transmit and receive filters help in mitigating the lSI (Inter Symbol Interference). In this paper, the effect of root raised cosine pulse shaping filter with different roll off factors in a 2xl MIMO-OFDM system employing 256 sub carriers is analysed. In particular, the work focuses on the selection of quantization bits, truncation length and rolloff factors in a practical WiMAX system. BER analysis at different rolloff factors is presented. To evaluate the performance of the proposed design, simulations were carried out in Matlab-Simulink.
