摘要： A multi-user detector for use in a CDMA receiver system includes a channel tap interpolator to generate interpolated channel taps for users of interest. The interpolated channel taps occur at integer multiples of a chip period from a sampling reference point. The channel tap interpolation allows detection processing to proceed in the chip domain, rather than in the sample domain, thus reducing the complexity of the multi-user solution significantly. In at least one approach, a number of low dimensionality 'virtual' users are defined based on the recursive property of the spreading sequences. Solutions may then be developed for the virtual users using conventional detection (e.g., MMSE) techniques.

摘要： A receiver includes a searcher to identify pilot signals within a received signal and a pilot tracking unit to continuously track pilot signals identified by the searcher. The pilot signals tracked by the pilot tracking unit may include pilot signals associated with an affiliated base station as well as pilot signals associated with non-affiliated base stations. In at least one embodiment, the pilot tracking unit continuously tracks most or all of the pilot signals identified by the searcher.

摘要： A synchronized frequency generating system (100) comprises a main crystal clock (102), for producing a basic frequency FB, a channel sampling phase locked loop (PLL) unit (104) connected to the main crystal clock, for converting the basic frequency FB into a channel sampling frequency FCS, a voice sampling PLL unit (108) connected to the main crystal clock (102), for converting the basic frequency FB into a voice sampling frequency FVS, a time tracking unit (106) connected to the channel sampling PLL unit (104), for detecting signal characteristics so as to determine a channel sampling frequency phase change value and a frame timing phase change value, and a phase controller (110) connected to the voice sampling PLL. The phase controller (110) receives channel sampling frequency phase adjustment data and determines a voice sampling frequency phase change value. The phase controller (110) provides the voice sampling frequency phase change value to the voice sampling PLL.

摘要： A wireless communication device receives CDMA signals and communicates with remote base stations in site selection diversity transmit (SSDT) mode. During communications with a primary base station, communication state parameters, such as signal to interference ratio (SIR) target values and carrier frequency estimates, are maintained for other base stations of an active set of base stations. The state parameters for communications with a selected base station are available for use after selection of a new base station. In.one embodiment, the communication state parameters are used for the selection of a base from the active set.
