Abstract:

Due to non-stationary noise such as burst, transmission and storage media in modern digital communications are imperfect. To reduce the effect of such noise, Error- Correction Codes are usually considered. Reed-Solomon codes are the most efficient codes to correct errors up to 2t. They can be classified as maximum distance separable codes (MDS). These codes have very good burst detection and correction capability. RS(n,k) can detect and correct all bursts of length up to m(b-1) + 1 over GF(p). This work concerned is with the simulation of binary stationary and non-stationary types of noise and then to compare the performance of Reed-Solomon code under a stationary environment and nonstationary environment. The results of computer simulations tests show that the performance of Reed-Solomon code in both stationary and non-stationary environments are almost the same and that is because, the test symbols is in the range (4-5)kilobytes. The results suggest that RS code may be used for error-correction in both stationary and nonstationary environments in the mentioned range.
