A block transmission wireless communication system (700), comprising: a preamble (100), including at least one repetition of a two-part training sequence (101-102) whereby bandwidth efficiency of said wireless communication system is improved due to elimination of a need for the training sequence to include any of the components selected from the group consisting of a cyclic prefix, a zero pre fix, and a zero post fix; a transmitter (602) that transmits said preamble (100) and the two-part training sequence included therein (101-102), at the beginning of each of a block time-domain and a block frequency- domain; and a receiver (603) that uses the training sequence (101-102) for time synchronization (SYNC), frequency offset estimation (FOE), AGC gain setting, timing error estimation and channel estimation (CE), wherein, bandwidth efficiency of the wireless communication system (700) is improved due to a peak-to-average power ratio (PAPR) that is lowered by at least 2 dB below conventional systems. |
