Wireless broadcasting using XOR coding

Abstract

Based on XOR coding, proposed is a proactive broadcasting for wireless broadcast systems where multiple faulty packets can be rectified at the cost of transmitting an additional coded packet. Since it greatly outstrips the conventional one in terms of BER performance, the proposed scheme can aggressively allocate the transmission rate to compensate for its throughput penalty. Numerical simulations show that the proposed scheme outperforms its conventional counterpart for about 5 dB SNR at a target BER of 10−3 for an OFDM system.
