    摘要: In an equalizer filter unit, the filter is divided into a plurality of sequential segments. While all the components of the equalizer unit multiply data signal groups by the a coefficient signal group, in only one segment are the coefficient signal groups updated. The data and the coefficient signal groups are periodically transferred to the next sequential filter segment while the filter segments are reconfigured in the original sequential order. In this manner, the each data signal group interacts with a coefficient signal group in the original sequential order. Because the coefficients are updated in only one of the filter segments, the amount of apparatus required for processing signal groups is reduced.

    摘要: Operands (90) that are represented in two's complement format are prepared for use in binary arithmetic. For each operand, it is determined (91, 93) whether an original value thereof is within a predetermined proximity of a maximum positive/maximum negative value boundary associated with the two's complement format. If any of the original operand values is within the predetermined proximity, all of the original operand values are adjusted (95) to produce respectively corresponding adjusted operand values (96) for use in a binary arithmetic operation.

    摘要: A method (70) of operating a wireless receiver (UST). The method receives a wireless communicated signal, wherein the signal comprises a first synchronization channel component. The method also correlates a synchronization channel value (PSC) to the signal to produce a plurality of correlation samples in response to a correlation between the synchronization channel value and the signal. Further, the method compares (72) the plurality of correlation samples to a threshold (τ) and stores as a first set of correlation samples selected ones of the plurality of correlation samples that exceed the threshold and are within a first time sample period, wherein each of the correlation samples in the first set has a corresponding sample time relative to the first time sample period. Finally, the method combines (74) a second set of correlation samples with the first set of correlation samples.

    摘要: The frequency hopping pattern of a first wireless communication device is modified such that each transmission (73) to a second wireless communication device is on a frequency (MSj+1) that the second device's normal frequency hopping pattern specifies for one of the second device's next several transmissions to the first device. This permits the second device to make quality measurements (54) on a frequency that the second device will soon use (51) for transmission to the first device.
