    摘要： A method for providing interference suppression in a communication device includes receiving a signal, determining if the received signal comprises a Gaussian Minimum Shift Keying (GMSK) or an 8 phase shift keying (8PSK) signal. Over sampling and inphase and quadrature phase separation with real-valued signal processing on the received signal is performed whenever the received signal is determined to be a GMSK signal. Oversampling with complex-valued signal processing on the received signal is performed whenever the received signal is determined to be an 8PSK signal. A receiver is also disclosed that provides for interference suppression.

    摘要： A receiver (MST) for use in a modulated communications system wherein data is communicated in a time-slotted format. The receiver comprises circuitry (22) for providing samples of a group of data from the time-slotted format and circuitry (46, 42) for determining a first set of channel estimates in response to a first set of the samples. The receiver also comprises circuitry (30) for first predicting decisions for data in the group of data in response to the first set of channel estimates and circuitry (46, 42) for determining a second set of channel estimates in response to the predicted decisions. Lastly, the circuitry for predicting is further for second predicting decisions for data in the group of data in response to the second set of channel estimates.

    摘要： A method described evaluates the pilot-to-data power ratio based on the values of the demodulated data at the output of a receiver such as a conventional maximal ratio combiner or an equalizer receiver. Since the data are not scaled to their particular decision grid, their distribution and statistics deviate from the ones defined by the known decision grid. Measuring these deviations of the statistics, the pilot-to-data power ratio and the appropriate demodulated data scaling can be accurately determined. Subsequent data processing may then commence.

    摘要： System and method for interference cancellation in a digital wireless communications system. A preferred embodiment comprises sampling a received signal wherein the received signal is real-valued, rotating the sampled received signal by a specified amount, extracting in-phase and quadrature phase streams from the rotated, sampled received signal, applying an interference suppression filter and combining the filtered streams. The output of the combining operation can be de-correlated (by whitening) if there is excessive correlation.
