Design and Development of Precoding Algorithm

Proposed work carries out the study of the Pre-coder and basic Transmitter – Receiver model. Transmitter and Receiver Simulink model is developed by estimating and equalizing channel. With this channel state information (CSI) Pre-coder is developed. Additive White Gaussian Noise (AWGN) channel is implemented in Simulink. Transmitter – Receiver model is built for simulation and performance evaluation. Suitable channel estimation and equalization algorithms are used for simulation. QPSK modulation is used, similarly demodulation techniques are used at the receiver. For different Signal to Noise Ratio (SNR) values Bit Error Rate (BER) is plotted. Least Square (LS) estimation and Zero Forcing (ZF) equalization algorithm for MIMO is implemented in Simulink.
