Abstract: A multimode rake receiver comprise a common antenna interface, arranged to at least receive in a first mode a first CDMA radio channel carrying information encoded according to a first baseband modulation standard and to receive in a second mode a second CDMA radio channel carrying information encoded according to a second baseband modulation standard; and a common signal processing path, at least arranged to process in the first mode the first CDMA radio channel and in the second mode the second CDMA radio channel, wherein the common signal path comprises a common descrambling and de-spreading unit and a common hybrid code generating unit arranged to provide to the common descrambling and de-spreading unit chip codes applicable in the first mode to the first CDMA radio channel and in the second mode to the second CDMA radio channel.

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: The delay associated with performing interference cancellation in a multi-user receiver is reduced by enabling partial decoding. According to an embodiment, interference is canceled from a received signal having signal contributions from multiple users by partially decoding a first codeword obtained from the received signal and transmitted by a first user via a first signal. The first signal is reconstructed based on the partial decoding of the first codeword and canceled from the received signal to yield a reduced-interference signal. A second codeword obtained from the reduced-interference signal and transmitted by the first user or a second user via a second signal is at least partially decoded. In one embodiment, the first codeword is partially decoded by puncturing one or more coded bits of the first codeword and decoding the first codeword based on the one or more punctured coded bits and estimates of the remaining coded bits.
Abstract translation: 通过启用部分解码来减少与多用户接收机中的干扰消除相关联的延迟。 根据一个实施例，通过部分地解码从接收到的信号获得的并由第一用户经由第一信号发送的第一码字，从具有来自多个用户的信号贡献的接收信号中消除干扰。 基于第一码字的部分解码并从接收信号中消除第一信号以产生减小干扰信号。 从所述减小干扰信号获得并经由所述第一用户或第二用户经由第二信号发送的第二码字被至少部分解码。 在一个实施例中，通过对第一码字的一个或多个编码比特进行删截并基于一个或多个穿孔编码比特和剩余编码比特的估计来对第一码字进行解码来对第一码字进行部分解码。

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.
