Error free transmission is the main aim of wireless communication. However nowadays with the increase in multimedia services there is a demand for ever increasing data rates. To reduce the bit error rate forward error correction methods (FEC) methods are now employed. In this paper we compare the BER performance of 16-QAM and 64-QAM modulation techniques with and without interleaving process. Also further we analyze the performance of MIMO OFDM system using OSTBC coding technique and compare it with convolution coding.

Forward Error Correction (FEC)

OSTBC Coding

Convolution Coding

In this paper we compare the performance of MIMOOFDM system in terms of BER using Forward Error Correction codes on AWGN channel. Here Convolutional codes are used as FEC codes. We evaluate Bit Error Rate of convolutional codes for 16-QAM and 64-QAM modulation schemes and compare them with OSTBC code. Results show that BER performance is improved when OSTBC coder is used. Also BER performance is further enhanced when interleaving is performed for both the modulation techniques.
