A method for generating a wireless waveform for use in a wireless communication system, a wireless communication system and computer program products thereof.

摘要

The method comprises the generation of a waveform for application in the wireless communication system characterized by significant phase noise, Doppler spread, multipath, frequency instability, and/or low power efficiency by at the transmitter side: creating a discrete-time instantaneous frequency signal f [ n ]; appending a cyclic prefix with length L CP to the beginning of the discrete-time instantaneous frequency signal f [ n ] ; constructing a discrete-time unwrapped instantaneous phase Æ[ n ]; constructing a discrete-time complex baseband signal, and appending at the beginning a Constant Amplitude Zero Autocorrelation, CAZAC, signal of length L CP for multipath detection; and passing the constructed discrete-time complex baseband signal through a digital-to-analog, DAC, converter to yield the continuous-time radio frequency signal s ( t ) after conversion to the carrier frequency.
