Title:
ハードリミットされた信号についてのチャネル推定および等化
Document Type and Number:
Japanese Patent JP5430661
Kind Code:
B2
Abstract:
The present invention provides a method and apparatus for channel estimation when the amplitude of a received signal is hard-limited. A channel estimator computes amplitude estimates for the received signal based on the phase samples of the received signal. The amplitude estimates may comprise the expected values of the amplitude given the phase samples. The channel estimator then computes revised channel estimates based on the amplitude estimates and the phase samples. The process may be performed iteratively to refine the channel estimates during each iteration.
