Analysis and Measurement of BER and SNR for Different Block Length in AWGN and Rayleigh Channel

Rapid change in the technology for seamless transmission of data at very high rate poses a great challenge for system designers. Signal is highly affected by the Noise and Error, reliability of the signal in the communication system is directly affected by the noise. Different types of Error control and correction codes are used for analyzing and controlling the error in the signal. Signal is directly affected by the Noise or error; it will change the reliability of the communication system. The occurrence of the errors is controlled by the Error control coding procedure. Shannon coding is also used for the error correction in the signals. The amount of redundancy added in any signal is increased as per the increment in the delay. In this paper, the author proposes a new interleaver for tolerating the latency situation and increasing the performance. It becomes more important to design and analyze the performance of interleaver for turbo code. It presents the comparative analysis of turbo code performance over an interleaver for various block lengths for two different types of channel which is AWGN and Rayleigh channel. It also provides the comparative analysis for the different fading channels.
