摘要

研究了带限BPSK微蜂窝系统中共信道干扰下最大比组合的中断和误码率分析。假设一个Nakagami/Rayleigh衰落模型。采用了频谱提升余弦和波约-坦-达门脉冲形状。导出了干扰功率相等和不同时中断概率的精确封闭表达式。利用共信道干扰的高斯近似，导出了平均误码率表达式。用蒙特卡罗仿真验证了高斯近似。结果对任意分集顺序和期望的用户衰落参数都是有效的。假设缓慢平坦衰落、异步定时和独立衰落增益。

Precise performance analysis of MRC diversity in microcellular systems with cochannel interference

The outage and BER analysis of maximal ratio combining for bandlimited BPSK systems in microcellular system with cochannel interference is considered. A Nakagami/Rayleigh fading model is assumed. Spectrum raised-cosine and Beaulieu-Tan-Damen pulse shapes are employed. Exact closed-form expressions for outage probability with equal and distinct interferers powers are derived. An average bit error rate expression is derived using Gaussian approximation of the cochannel interference. Monte-Carlo simulation is used to validate the Gaussian approximation. The results are valid for arbitrary diversity order and desired user fading parameter. Slow flat fading, asynchronous timing and independent fading gains are assumed.
