Abstract: A communication system provides wireless communication in a coverage area and includes a base station (100) and a mobile station (290). The base station (100) has a plurality of sectors (210, 220, 230, 240, 250, 260) where a corresponding plurality of pilot signals (212, 222, 232, 242, 252, 262) are transmitted. A sector (210) transmits a forward link signal (211) for communicating to the mobile station (290). The mobile station (290) transmits a reverse link signal (215) and a message signal including a list of a plurality of candidate sectors for a soft hand-off routine. A method and apparatus of determining the candidate list includes measuring reverse link signal (215) which are received at said plurality of sectors. Then, comparing reverse link signal level received at sector (210) to the reverse link signal levels received at all other sectors of said plurality of sectors (210, 220, 230, 240, 250, 260).

Abstract: A peak-reducing waveform is estimated and summed with a composite signal to reduce the peak-to-average power ratio of the composite signal. The estimate of the peak-reducing waveform is modified to have Walsh code components orthogonal to the assigned Walsh codes. An iterative process of estimating subsequent peak-reducing waveform is implemented to produce a peak-reducing waveform which, when summed with the composite signal, results in a composite signal having a peak-to-average ratio at a desired level and thus does not have the effects of remodulating the assigned Walsh codes. Constraints on the magnitude of the unassigned Walsh code components can be included for controlling the power level under the unassigned Walsh codes.
