Abstract: In an SC-FDE system, in accordance with FDPMT, a transmitter may be configured to replace data carried by one or more signals, e.g., one or more sub-carriers, with the data included in a pilot frequency sequence. The starting position of the pilot frequency sequence may affect the BER value of the system. The transmitter may then be configured to choose a proper starting position for the pilot frequency sequence so that the BER of the overall system may be minimum.

Abstract: A transmitting end of an Orthogonal Frequency-Division Multiplexing (OFDM) wireless communication system may generate a training sequence and attach the training sequence to a data sequence that contains information data. A receiving end of the OFDM wireless communication system may identify a starting position of the data sequence and further extract the data sequence.
