EFFICIENT WIRELESS VIDEO TRANSMISSION VIA LINKLAYER FEC FOR VIDEO COMMUNICATIONS

Abstract

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.
