Methods and apparatus for determining minimum cyclic prefix durations
Individual analog subcarrier signals are generated by processing one or more digital signals, e.g., symbols plus a cyclic prefix for each symbol, corresponding to the subcarrier to generate an analog subcarrier signal there from. In one embodiment, digital signals for each individual subcarrier are received and processed in parallel. Each generated analog subcarrier signal is subject to amplification, e.g., power amplification, prior to being combined with the other analog subcarrier signals. Power amplified subcarrier signals are generated in parallel, or, alternatively, some of the circuitry used to generate one subcarrier signal can be used on a time shared basis to generate one or more additional subcarrier signals with the results being buffered prior to being combined to form the transmitted signal.
