Receiver for MUROS adapted to estimate symbol constellation using training sequences from two sub-channels

摘要

A receiver is provided that is configured to estimate the symbol constellation of a signal modulated using a quaternary symbol constellation where data is transmitted to two mobile stations multiplexed on a shared channel comprising two branches, where the branches correspond to the real and imaginary parts of one complex-valued baseband signal. The receiver is configured to demodulate the modulated signal using the training sequences from both sub-channels.

1. A method of receiving modulated data in a mobile station, where the received data is modulated using a quaternary symbol constellation and where data is transmitted to two mobile stations multiplexed on a shared channel comprising two sub-channels, where the sub-channels correspond to the real and imaginary parts of one complex-valued baseband signal, said method comprising:
estimating the symbol constellation of the quaternary symbol constellation modulated signal using training sequences from both sub-channels; and demodulating the modulated data using the estimated symbol constellation.
