초록

This paper has been studied the design of 16-QAM demodulator used in broadband wireless local loop subscriber station. In B-WLL systems, transmission signal experience the inter symbol interference(ISI) due to multipath, frequency offset of RF/IF local oscillator and phase offset. In this paper, we discuss the effective data recovery algorithm for 16-QAM demodulator to compensate the distorted signal from ISI, frequency offset and phase offset.
