    摘要: Provided is a method and apparatus improving a deterioration of a gain flatness and a phase characteristic that may be incurred while a baseband signal is transformed into a immediate frequency (IF) signal and a radio frequency (RF) signal in a broadband wireless communication system. A sub-band extractor may divide the broadband signal into multiple sub-band signals, may pre-compensate for a gain and a phase delay of each sub-band signals in the baseband, and may combine the pre-compensated sub-band signals into the single broadband signal and thus, the deterioration of the gain flatness and a phase delay flatness that may be incurred while the broadband signal is transformed into the IF signal and the RF to signal, may be improved.

    摘要: Disclosed are an apparatus, method, and system for transmitting and receiving high-speed data in point-to-point (P2P) fixed wireless communication. In an apparatus for transmitting high-speed data in P2P fixed wireless communication, an amplitude zero autocorrelation waveform (CAZAC) sequence generator generates and outputs a CAZAC sequence. A frame generator generates a frame in which the CAZAC sequence is arranged as part of a preamble before a payload including actual data. A continuous wave (CW) generator generates and outputs a CW signal. A multiplexer receives the CW signal output by the CW generator, and arranges and outputs the CW signal in a position before a signal output by the frame generator.
