Frame Synchronization for N-oncoherent Demodulation on Flat Fadling Channels
Arkady Kopansky, M. Bystrom · 2000
In this work we consider the prob- lem of locating a known periodically embedded synchronization pattern in random data, which is subject to flat fading and additive white Gaus- sian noise. We derive the maximum likelihood rule and its high-SNR approximation for the case of noncoherent demodulation and show experi- mental results for the slow-fading Rayleigh chan- nel. It is shown that the well-known correlation rule performs substantially worse than maximum- likelihood rule derived here.
