    摘要： Methods and systems for estimating and canceling pilot interference in a wireless (e.g., CDMA) communication system. In one method, a received signal comprised of a number of signal instances, each including a pilot, is initially processed to provide data samples. Each signal instance's pilot interference may be estimated by despreading the data samples with a spreading sequence for the signal instance, channelizing the despread data to provide pilot symbols, filtering the pilot symbols to estimate the channel response of the signal instance, and multiplying the estimated channel response with the spreading sequence. The pilot interference estimates due to a plurality of interfering multipaths are accumulated to derive the total pilot interference, which is subtracted from the data samples to provide pilot-canceled data samples. These samples are then processed to derive demodulated data for each of at least one (desired) signal instance in the received signal.

    摘要： Methods and mobile stations for transmitting, receiving and processing peer-to-peer communication signals without a base station or network element. A transmitting mobile station may alternate two or more long code masks to generate one or more pseudorandom noise (PN) codes to spread data for transmission. A receiving mobile station receives the spread data and achieves synchronization with the transmitting mobile station.

    摘要： A camera based measurement system which can automatically determine tailor body measurements with one camera, few pictures and without requiring the customer to wear special garments. The present invention will automatically detect the neck and other body features and can perform the function with a single camera, and a relatively small number of views.
