A system that includes at least one component adapted to execute at least one application, characterized by including a controller adapted to receive at least one load indication of at least one component of the system and to selectively alter at least one control parameter of a voltage and clock frequency management scheme; whereas the system is adapted to apply the voltage and clock frequency management scheme. A method for controlling voltage level and clock frequency supplied to a system, the method includes receiving at least one load indication of at least one component of the system; characterized repeating the stages of: selectively altering at least one control parameter of a voltage and clock frequency management scheme; and applying the voltage and clock frequency management scheme.

System and method for controlling voltage level and clock frequency supplied to a system

A configurable receiver and a method for configuring a receiver, the method includes: (i) evaluating multiple nonzero taps allocations, wherein each nonzero taps allocation evaluation includes: (i.a) allocating nonzero taps between multiple sparse equalizers, wherein different sparse equalizers are expected to equalize signals transmitted over different channels; wherein each channel is associated with an information source out of multiple information sources and with a receiving antenna out of multiple receiving antennas; wherein the number of nonzero taps is bounded by a upper limit; and (i.b) calculating multiple channel reception parameters of the multiple channels in response to the nonzero taps allocation; and (ii) configuring the receiver in response to a comparison between reception parameters obtained during different nonzero taps allocations.

Configurable receiver and a method for configuring a receiver

A method of processing a code division multiple access signal comprises receiving a CDMA signal; processing the received CDMA signal with a CDMA detector; and extracting control channel information from the processed signal. The extracted control channel information is used to equalize a subsequent received CDMA signal, to make estimation of equalizer coefficients more reliable and increasing average data throughput.

Wireless communication unit and method for processing a code division multiple access signal

Known chip equalizers for Wideband-Code Division Multiple Access (W-CDMA) employ a co-efficient calculator that implements a Minimum Mean Square Error (MMSE) solution to a least squares technique for obtaining equalizer coefficients in response to receipt of a pilot sequence. However, this solution results in an undesirably high processing overhead in downlink receivers operating in a W-CDMA communications system. Consequently, the present invention provides a computationally simpler technique to calculate equalizer coefficients by implementing a minimum-norm solution to the least squares problem.
