Abstract
A hybrid data transmission frame format for a hybrid single-carrier modulation and OFDM carrier modulation MIMO system and corresponding transmission/reception methods and devices. A transmitter employs single-carrier modulation for preambles and signaling fields via a single-carrier signal generator to produce single-carrier transmission sequences of transmission links. While to employs the same sampling rate to process all the data so as to match a receiver, the sampling rate of the single-carrier transmission sequences needs to be processed into being identical to that of OFDM via a pulse shaping multiphase filter before entering a digital-to-analog converter; the transmitter employs an OFDM modulation mode to transmit data field segments via an OFDM signal generator; and a data receiving process of the receiver is opposite to a data transmitting process of the transmitter.
