Channel Estimation and Equalization Using DF Relay

Silpa S Kishore [2] | Jubin Mathew [3]


Abstract: The multiple input multiple output (MIMO) is a technique for sending and receiving more than one data signal on the same radio channel at the same time via multipath propagation. Multipath propagation thus multiplying the capacity of the radio link. Hence MIMO has several advantages over the conventional single-antenna systems such as high data capacity and better diversity against channel fading. One of the important parameter to be obtained in the case of MIMO system is the channel state information. In this work we are implementing an algorithm called least mean square algorithm for the estimation of channel state information (CSI) in MIMO systems and is compared with the existing forward link quadratic estimation algorithm. Along with estimation, an equalization is also done in order to eliminate the effects of inter symbol interference (ISI) and noise while transmitting through the channel.
