摘要： Apparatus for reducing adjacent channel interference between proximate wireless communication units. Each wireless communication unit includes a digital baseband circuit and an analog baseband circuit. The digital baseband circuit includes at least one group delay compensation equalizer and at least one finite-impulse response (FIR) filter. The analog baseband circuit includes a radio (transmitter section), a power amplifier and a narrowband filter. The narrowband filter compensates for deficiencies of the power amplifier including distortion and radio frequency (RF) power spill over. The group delay compensation filter compensates for undesired characteristics (e.g., group delay variation) exhibited by the narrowband filter.

摘要： A method and apparatus for processing multiple wireless communication services in a receiver (100). A receiver (100) receives more than one wireless communication service simultaneously via a wireless interface. Each service is transmitted via a different carrier frequency band. The multiple received carrier signals are down-converted to an intermediate frequency (IF) band using a mixer (110, 116) and a local oscillator (LO). The LO and sampling frequencies are adjusted such that the converted IF band signals of the input signals are spectrally adjacent or overlapping each other to some degree. SINAD of the services is measured at each of a plurality of spectrally overlapping conditions. The LO frequencies and the sampling frequency are then adjusted based on the SINAD measurement results.

摘要： Method and apparatus for transfer of signals from multiple antennas down to baseband over a common radio frequency (RF) chain. Antenna selection having greater flexibility and applicability to both uplink and downlink wherein priority is given to the antenna receiving a better quality signal. Measurements are taken during each time slot to determine the weighting to be given to the antenna with the better quality signal. Techniques and apparatus are provided to take measurements over a range of intervals from time slots to single symbols, for example, to select the best signal the techniques described herein may be used individual, and in some cases are combined to receive additional benefits in efficiency.
