RECEIVER, METHOD AND PROCESSOR PROGRAM PRODUCT FOR RECEIVING MODULATED CODED SIGNALS, NON-LINEAR COMPENSATOR FOR USE IN THE RECEIVER, AND TRANSCEIVER COMPRISING A TRANSMITTER WITH A DIFFERENTIAL CODER AND A PHASE-SHIFT-KEYING MODULATOR

摘要

(Differential 4) phase-shift-keying demodulator consists of (4) and decoder (19) differential detector 10 in the receiver, including, in order to reduce the number of incorrect decisions and improve the decoding process, the decoder output signal ratio for compensating for interference, wherein (part of) the linear compensator 20 are provided . Non-linear compensator 20 comprises a remover (21, 23) for removing, wherein the channel estimator (22) and the decoder output signal to predict the coefficients of terms of decoder output signals. The receiver is designed for a Bluetooth environment. Decoder output signal u _k = Ab _k + Bb _k-1 + Cb _{k + 1} + Db _k ^* + Eb _k-1 b _k + Fb _k b _{k +1} + Gb _k-1 b _k b _{in the k + 1} + H, Eliminator, u _{To reduce b} sub k for extracting from the complexity of what k /sub, wherein H- and removes wherein B-. Slicer, so that the possible values of decoder output signals can be better for another nine minutes, separate the compensated decoder output signals to further compensate said decoder output signal.
