To fulfill the extensive need of high data rate transfer in today's wireless communication systems such as WiMAX and 4G LTE (Long Term Evolution), the turbo codes gives an exceptional performance. They have allowed for near Shannon limit information transfer in modern communication systems. As the performance of these codes increases, their decoding complexity is also increases and so the power consumption. To reduce this complexity without decreasing its BER (Bit Error Rate) performance a novel modification over SOVA (Soft output Viterbi Algorithm) is proposed in this paper.
