Abstract:
1. A communication method, comprising: storing a cyclic prefix duration value in a memory; operating a plurality of N sinusoidal signal generators to generate first through Nth subcarrier signals from first through Nth digital symbols; operating each of a first through Nth cyclic prefix generation modules to access the stored cyclic prefix duration value and add a cyclic prefix to a corresponding one of the first through Nth subcarrier signals, the added cyclic prefix having the duration specified by the stored cyclic prefix duration value; performing an amplification operation with an amplification module on each of the first through Nth subcarrier signals and added cyclic prefixes to produce first through Nth amplified subcarrier signals, wherein N is a positive integer; and operating a combining circuit to combine the first through Nth amplified subcarrier signals to generate a frequency division multiplexed transmission signal.
