Performance of multi-carrier M-ary QAM for high rate transmission in wireless communications

High bit rate data transmission is required for video, high quality audio, and mobile ISDN services in wireless communications. The performance of multi-carrier M-ary QAM for high rate transmission is evaluated in wireless communications. The effects of delay spread and cochannel interference is taken into account. It is shown that multi-carrier M-ary QAM with fading compensation techniques and diversity reception achieves reliable communications for high bit rate data transmission in wireless communications.
