Performance of multiple-dwell pseudo-noise code acquisition withI-Q detector on frequency-nonselective multipath fading channels

摘要

Multiple-dwell serial search pseudo-noise (PN) code acquisitionwith noncoherent I-Q detector is analyzed for frequency nonselectiveRayleigh and Rician fading channels. Optimum mean acquisition time isused to evaluate the effects of multipath fading and frequency offset.Moreover, the performance of the I-Q detector is compared with that ofthe square-law detector
