Simulation of Fading Channel and Burst Error Behavior of State-3 Memoryless Markov Model

The paper contain a report on simulation of fading channel using Markov Model through a very simple and effective approach, The study established the successful application of Discrete time Simulation in fading channel by applying a tri-states memory-less Markov Model. We generated Four Matlab programs to simulate the Markov Fading Channel and successfully implemented the generated code through the model. Thus, this validates the applicability of the Markov Model in the simulation of fading channel. The probability of error varies according to any change that could happen in the probability of moving from one state to another. Considering 20 points around the standard probability of transition, each point is the average of 100 cycles of the same probability of transition, For Burst Error Behavior of State-3, Simulations have been performed with the data streams consisting of 4.8 Megabits have been directed through the Markov Channel in different test conditions. The length of each error as well as its frequency of occurrence has been recorded. To better conform to industrial application where long data stream would be cut into data-packets of fixed length before transmission, the 4.8 Megabits data stream has been cut into various data-packets sizes of 300 bits, 1200 bits, 4800 bits and 19200 bits for comparison purpose. These particular packet sizes have been chosen in consideration of the use of RC-Interleave in subsequent simulations and for Error-CorrectionCoding and Interleaved Coding Scheme. We also studied the burst error behavior of State-3 memory-less Markov Model and presented the use of Error-CorrectionCoding with Interleaved scheme which is justified by the illustration of consistently lower Bir-Error-Rate.
