Abstract
A synchronous coherent orthogonal frequency division multiplexing, SC-OFDM, system, method, software and device include a plurality of SC-OFDM transmitters and a plurality of SC-OFDM receivers. Each of the plurality of SC-OFDM transmitters is synchronized to a reference where the reference is derived from a common source, for transmitting SC-OFDM signals. The plurality of SC-OFDM receivers is arranged to receive the SC-OFDM signals from at least one of the plurality of SC-OFDM transmitters. The SC-OFDM signals each have a cyclic extension, and the SC-OFDM signals from each SC-OFDM transmitter include at least one pilot code in accordance with a predetermined pilot code scheme.
