In this letter, we present a moment generating function (MGF) based performance analysis of generalized selection combining (GSC) receivers operating over independent and identically distributed (i.i.d.) K fading channels. Analytical expressions for the marginal MGF of the signal-to-noise ratio of a single diversity branch for integer plus one-half values of the fading parameter are obtained and used to efficiently evaluate the average error probability of GSC receivers. 相似文献

Antenna subarray formation is a novel RF pre-processing technique that reduces hardware complexity of multiple-input multiple-output systems while alleviating the performance degradation of conventional antenna selection techniques. With this method, each RF chain is allocated to a linear combination of the responses of a subset of the available antenna elements, which is performed in the radio frequency domain. A novel, analytical, suboptimal algorithm is introduced for receive antenna subarray formation based on instantaneous channel information that maximises the effective channel capacity. 相似文献
