OPEN LOOP CYCLOSTATIONARITY BASED TIMING RECOVERY FOR ACCELERATED TIMING ACQUISITION IN FREQUENCY SELECTIVE CHANNELS

摘要

An error between the rate fsym at which data are received and the rate fs at which the data are sampled in is determined by processing a received signal with a nonlinear operator, performing a DFT on the processed signal to produce a plurlaity of DFT bins each characterized by a respective frequency, determining a dominant spectral component k0 from at least two of the DFT bins whose frequencies are substantially close to the frequency of the dominant spectral componant k0, and determining the data rate fsym from the dominant spectral componant k0.
