Channel State Information Estimation using Golden Ratio Principle in Downlink of Land Mobile Satellite System

A channel estimation technique based on golden ratio principle is developed to reduce the effect of co channel interference in a satellite communication system with VBLAST processing architecture in a multi user scenario. Performance evaluation parameters indicate an improvement in the error reduction for the estimated data vector in comparison to the optimal detection technique such as ML detector. Performance parameter index namely, MMSE estimator with numerical value of 0.2463 for the system under consideration is a close approximation to the lower bound of an unbiased estimator. An efficient satellite system model with channel estimation technique based on golden ratio principle is proposed providing reduced BER and high transmission rate.
