OFDM COMMUNICATIONS METHODS AND APPARATUS |
摘要 |
FDM signal communication methods and apparatus are described. In accordance with the invention FDM signals are generated in the time domain with symbols being mapped to specific point in time. Training symbols may be included in the transmitted FDM signal to facilitate symbol recovery. An exemplary receiver receives the FDM signal from the communications channel, converts it into the frequency domain, and then filters it in the frequency domain to eliminate tones corresponding to other users. The filtered signal free of MAC interference is then converted into the time domain where channel estimation and compensation operations are performed. After channel compensation symbol recovery is performed in the time domain. |
