Performance Evaluation of Concatenated Codes applied in Wireless Channels

This paper provides the design and graphical illustration of the error rate performance obtained on a frequency selective Raleigh fading channel. The system applied for using the concatenated codes in which the outer code is a Reed-Solomon code and the inner code is either a (Reed- Solomon, Hamming, or Bose- Chaudhur- Hocquenghem- (BCH)) codes. The performance comparison of these three types of concatenated codes is made on the basis of the same bandwidth expansion factor. The concatenated code system using Reed-Solomon codes as an inner code offers better performance than the concatenated code system using BCH and Hamming Inner codes.
