MIMO Systems and Transmit Diversity 1 Introduction

WebCooperative diversity: Achieves antenna diversity gain by using the cooperation of distributed antennas belonging to each node. Combiner techniques [ edit ] An important element in communication systems applying diversity schemes is the "Combiner", which processes the redundantly received signals. Diversity gain is the increase in signal-to-interference ratio due to some diversity scheme, or how much the transmission power can be reduced when a diversity scheme is introduced, without a performance loss. Diversity gain is usually expressed in decibels, and sometimes as a power ratio. An example is soft handoff gain. For selection combining N signals are received, and the strongest signal is selected. When the N signals are independent and Rayleigh distributed, the expected d…
