摘要

In this paper, an improved transmission scheme for high speed communication systems is introduced. This scheme combines a low complexity discrete bit loading algorithm with a simplified Maximum Ratio Combining (MRC) pre-equalization scheme at the transmitter for maximizing the data throughput of Orthogonal Frequency Division Multiplexing (OFDM) systems. Results of computer simulations show that pre-equalization is a very effective scheme for improving the performance of the proposed bit loading algorithm, especially, in high speed communication systems.
