摘要
A practical adaptive bitloding scheme based on greedy algorithm is presented for MQAM modulation MIMO-OFDM wireless system. Singular Value Decomposition is used for the decomposition of spatial multiplexing channels into parallel subchannels, and eigenvalues are used for optimal design of bit loading and power distribution among subchannels. The greedy algorithm used in bitloading of OFDM systems is then extended and simplified to the multiple antennas situation.
