Performance Analysis of Compressive Sensing based LS and MMSE Channel Estimation Algorithm

In this paper, we have developed and implemented Minimum Mean Square Channel Estimation with Compressive Sensing (MMSE-CS) algorithm in MIMO-OFDM systems. The performance of is analyzed by comparing it Least channel estimation compressive sensing (LS-CS), (LS) (MMSE) algorithms. It observed that the MMSE-CS terms Bit Error Rate (BER) metric definitely better than LS-CS LS algorithms at par MMSE algorithm. Moreover role theory accentuated fact only a very small number coefficients are sensed to recreate transmitted data faithfully as compared
