LOG LIKELIHOOD ESTIMATE BASED ON CHANNEL ESTIMATION ERRORS DETERMINED BY SAFETY SUBRANGES

摘要

Methods for detection and decoding with help of this method including subranges are declared. A receiver receives symbols of control signals which are received, for subranges of control signals, and data symbols which are received, for data subranges. Channel evaluations are introduced, which are based on symbols of control signals which are received, with zeroed subranges of control signals, filled with nulls. Data detection is realized on symbols of data which are received, with help of channel evaluations for obtaining evaluations of data symbols. Noise evaluations and errors evaluations caused by zeroed subranges of control signals are introduced. Thereafter, LRP ratio based on data symbols evaluations, channel evaluations, noise evaluations and errors evaluations are calculated. LRP ratio is undergone reverse interlacing and decoding for decoded data acquisition.
