: In this paper, we propose two dynamic error control schemes and apply them to the multichannel data
communication system. The proposed schemes are based on the basic Stop-and-Wait ARQ and Selective Repeat ARQ
protocols, The former and latter are used for the error controls in a round-trip time and among the multiple channels
in a slot, respectively. The state of each channel is assumed as Markov chain with two states. The operations of the
proposed schemes are described and their performances are evaluated through computer simulation. The numerical
results show that the performances of the proposed schemes are improved remarkably comparing with the traditional
scheme.
