Abstract :
This paper studies the bit loading algorithm for adaptive OFDM transmission system, and proposes an improved scheme called shifting-threshold algorithm. Using computer simulations, we show that the OFDM system employing the shifting threshold algorithm can enhance bit rate. On BER performance, the shifting threshold algorithm is better than fixed threshold algorithm.
