A Novel Approach for Performance Analysis of Wireless Receiver with Selection Combining in Weibull Fading Channel

摘要

We provide a unified analysis of wireless receiver in Weibull fading with arbitrary parameters. With the aid of Moment Generating Function (MGF) approach and Pade approximation (PA) technique different performance measures such as outage probability and Average bit error rate have been considered for analysis. We first find the novel closed-form rational expressions for the MGF of the output SNR of the wireless receiver with and without diversity combining. The error rate performance of different multilevel modulations such as MDPSK, MQAM and MPSK along with outage probability evaluation has been done for both integer and non-integer values of Weibull Fading parameter. Our results are validated through computer simulations which shows perfect match.
