Abstract: This invention relates to a method and an apparatus for code activation, and a computer program and a storage medium thereof. A combined channel impulse response for each code is calculated based on a channelization code, a scrambling code and a channel impulse response corresponding to the code; a statistical result of the correlations between each interference code and all user codes is obtained; an active interference code number is determined; the determined number of interference codes, are activated, wherein a selection of which interference codes to activate is based on the statistical result. In some embodiments of this invention, the interference codes having a close correlation with the user codes may be selected to be activated, thereby the performance of joint detection is improved. In some embodiments of this invention, the complexity of the subsequent joint detection will be remarkably reduced on the premise of ensuring the performance of the joint detection.

Abstract: Certain aspects of a method and system for achieving space and time diversity gain are disclosed. Aspects of one method may include modifying a generalization code of at least one pilot channel, to measure signal strengths for each of a plurality of received multipath signals. A portion of the plurality of received multipath signals may be combined based on the measured signal strengths. The signal strengths of the plurality of received multipath signals may be measured on a primary pilot channel by assigning its generalization code to zero. The signal strengths of the plurality of received multipath signals on a secondary pilot channel may measured by assigning its generalization code to a non-zero value.

Abstract: Wireless devices, transmitters, systems and methods are provided that have a narrow band signalling channel and a wide band channel, for example an OFDM channel. In order to save power, the wireless device is nominally powered down with the exception of a receiver specific to the narrow band signalling channel. Once instructed to do so over the narrow band signalling channel, the wireless device wakes up the rest of its wide band receive circuitry.

Abstract: A Multi-Code (MC) Code Division Multiple Access (CDMA) receiver receives N (where N>1) encoded signal channels over multiple air signal paths. The MC-CDMA receiver receives and demodulates the N encoded signal channels into N signal samples and includes a common circuit for time-sharing an accumulator, for accumulating the N signal samples, among a plurality of second correlators. Each of the plurality of second correlator means utilizes the time-shared accumulator to accumulate samples from each of the N signals which are then decoded into an associated one of the N signal channels.
