Working of the turbo code depends on their frame size but, the bit error rate (BER) action of turbo codes can be improved by increasing the frame size. Miserably, the frame size increases produce some defects such as the increase of transmission time and decoding delay. To overcome these drawbacks, we are using FTN scheme. In this scheme we are using inter symbol interference (ISI), by using this method we achieved not only improves the BER performance but also reduces the decoding delay and transmission speed but noise is little bit more so reduces of it we are using pre coding method. By this method pre-equalizer is used. We consider the baseband system model for pre coded FTN transmission scheme under an AWGN channel the system model is common for both linear and non-linear preequalization methods. by this method we reduce the mainly noise and as well as increase the transmission speed and decoding latency.
