Abstract :
In multiple input multiple output (MIMO)- orthogonal frequency division multiplexing (OFDM) communication system, OFDM spreads the data over a number of carriers which are at specific predefined frequencies and makes a reduction or elimination of the Inter Symbol Interference. But the prime concern of OFDM system is the value of ergodic capacity of the communication system. To overcome this drawback, a proposition is given for a communication model with Algebraic Space Time Codes encoder and Minimum Mean Square Error equalizer. We have inculcated a comparative analysis of the different outcomes i.e. ergodic capacity with several values of signal to noise ratio by incorporating different number of antennas available from primitive technologies and thus the obtained results are overwhelmed than all the others before.
