摘要

研究了智能天线技术作为提高OFDM无线局域网物理层性能的一种方法。为此，本文比较了采用不同参数的预fft和后fft阵列处理的IEEE 802.11a WLAN系统的智能天线架构。在IEEE802.11a系统的Simulink模型上，采用基于5ghz频段宽带信道实测的时空信道建模方法进行了仿真。评估和比较了在LOS和NLOS信道情况下QPSK/16QAM调制的原始误码率性能

Comparison of the Smart Antenna Architectures for OFDM-WLAN Systems in a Rich Multipath Environment based on a Spatio-Temporal Channel Model

The smart antenna technique as a method of improving the physical layer performance of OFDM WLANs is studied. For this purpose, a comparison of the smart antenna architectures for IEEE 802.11a WLAN system using pre-FFT and post-FFT array processing with different parameters is represented. Simulations are performed on a new Simulink model for IEEE802.11a system using a spatio-temporal channel modeling which is based on the measured wideband channels in the 5 GHz band. Raw bit-error-rate performance for QPSK/16QAM modulations at LOS and NLOS channel scenarios are evaluated and compared
