    摘要: A receiver may train its equalizer using consecutive pilot bursts, divide the traffic between the consecutive pilot bursts into multiple sub-segments, and interpolate the trained equalizer coefficients to obtain the coefficients for equalizing one or more of the sub-segments. The receiver may also determine signal to interference and noise ratio (SINR) values based on each of the consecutive pilot bursts, and interpolate the SINR for decoding one or more of the sub-segments. The receiver may be an access terminal receiver operating in a code division multiple access (CDMA) cellular system.

    摘要: A method for interference reduction is described. The method is implemented in a wireless device. It is determined that a page is going to be received via a secondary receiver. It is also determined that a digital-to-analog converter (DAC) image from a transmitter will cause interference with the secondary receiver when the page is received. A sampling frequency of the DAC for the transmitter is changed so that there are not any DAC images from the transmitter that will cause interference with the secondary receiver.

    摘要: A method and apparatus for selectively clipping waveforms prior to transmission in a multi-carrier wireless communication system is provided. The design includes estimating peak values of the composite multi-carrier signal, determining a local threshold set including one local threshold for each carrier based on a configurable total threshold representing a maximum aggregate signal level for a sum of all signals to be transmitted over the multiple carriers, and clipping one signal to be transmitted over one carrier when the signal exceeds a corresponding local threshold and a sum of all signals to be transmitted over multiple carriers exceed the total threshold. Alternately, the design may include estimating peak signal values for signals to be transmitted in the multi-carrier system, and selectively clipping any signal wherein at least one peak signal value exceeds a local threshold and peak signal values for a sum of all signals to be transmitted exceed a global threshold.
