摘要：Orthogonal frequency division multiplexing is a popular modulation method in high speed wireless transmission. It removes the detrimental effect of multipath fading by partitioning the wideband fading channel into flat narrow band channels. For this purpose adaptive equalizer is used here. In this paper we will design the OFDM system with channel Equalization under the powerful concatenated turbo codes to it. This will help to maintain the system performance under a desired bit error rate, as there were errors occurring in burst form which eventually degrades the efficiency of the system .This paper deals with the optimization to analyze the comparative study of BER for the BPSK and DPSK (coherent and non-coherent) modulation scheme to achieve higher data speed and less probability of error for robust and reliable co mmunication under our proposed system model.
