Abstract :
While many researchers have focused on bit-loading algorithm itself, this paper introduces a way to implement bit-allocation in terms of Layer-2 protocol for improvement of commercial Wi-Fi networks. In this paper, a novel protocol is proposed to allow to implement a bit-allocation over time-varying wireless channels by using as small overhead as only one OFDM symbol.
