Summary :

A new class of codes defined as Separable Code has been considered to be successfully applied to a new error-control scheme called Type- Hyprid ARQ, which is based on the concept that some of the parity-check digits of the codes are sent to the receiver only when they are requested for error correction. Sevaral separable codes suitable to random error channels have been constructed and analyzed. In this paper, a new class of separable codes suitable to the burst error channels is constructed by modifying the Fire codes. Performance analysis of the codes based on the generalized Gilbert channel is given, showing that the proposed codes are superior to the Fire codes. Also, a new method of constructing a class of separable codes suitable to random error channels by puncturing linear block codes is given. It is shown that these codes are easier to implement than the known separable code.
