Abstract

In the context-aware mobile computing environment, the context-aware mobile computing devices adapt their behavior to available services which require different communication protocols by the type of transmitted data (e.g. video, voice, text and etc.). In this paper, we present a novel architecture for an adaptive Reed-Solomon decoder which can apply to context-aware mobile computing device to support various code specifications for heterogeneous communication protocols. This decoder can vary the length of the codeword, generate polynomials and correct erasures. For this decoder, we use a modified Euclidean algorithm based on a GF(28) finite field for the error locator polynomial. Also, this decoder can support any specification in the range of (1 ≤ n ≤ 255) for the codeword and (1 ≤ t ≤ 255) for the errors.
