    摘要: A “smart antenna” method and system for use in cellular networks where the wireless transmit receive unit and/or the base station utilize multi-user detection (MUD). The interference to and from other users is taken into consideration to maximize the desired signal while eliminating or reducing interfering signals, thereby increasing overall system capacity.

    摘要: A system for estimating carrier offset includes includes a transmitter configured to transmit a quadrature modulated signal, and a receiver. The receiver includes an input configured to receive the quadrature modulated signal, a local oscillator configured to generate cosine and sine waves at a carrier frequency of the quadrature modulated signal, at least one cosine mixer configured to generate a carrier frequency demodulated output, at least one sine mixer configured to generate a carrier frequency demodulated output, a plurality of lowpass filters configured to filter the demodulated output of the cosine and sine mixers to produce filtered cosine and sine signal components, and a carrier offset detection processor to estimate a carrier offset between the carrier frequency and a local oscillator frequency based on the filtered output of the lowpass filters.
