EFFICIENT WIRELESS VIDEO TRANSMISSION VIA LINKLAYER FEC FOR VIDEO COMMUNICATIONS

In this paper, new analysis and performance of robust error-model are presented for mpeg-4 video stream over wireless point-to-point network. analytical expressions assume a noisy wireless environment causing frequent and random bit errors associated with packets. by this model, the temporal video scalability can be evaluated under tcp-friendly rate control (tfrc) transmission when the bose-chaudhuri- hochquenghem (bch) channel coding is employed as a forward-error- correction (fec) at a radio link layer. a fec provides an efficient throughput access on wireless network. the numerical results clearly indicate that a quality of service (qos) can be improved at low channel snr region when the maximum channel coding throughput is achieved.
