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： A novel and improved method and system for paging a cellular telephone or other wireless terminal using two paging channels that reduces standby mode power consumption described. In one embodiment of the invention, a minimally encoded quick paging channel is established over which short, quick page messages are transmitted during one of a set of quick paging slots. The quick page message indicates that a communications request has been received, and that the receiving communication terminals should process a highly encoded full paging channel over which more detailed, full page messages are transmitted during the next full paging slot. A terminal monitors full paging channel only after a quick page message has been received on the quick paging channel.

摘要： A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.
摘要翻译：使用动态共享前向链路信道（或“数据”信道）将组播数据发送到一组无线设备，例如使用用于数据信道的公共长码掩码。参考功率控制（PC）位也在数据通道上发送并用于信号质量估计。共享的前向链路控制信道用于向各个无线设备发送用户特定的信令，例如对于每个无线设备使用时分多路复用（TDM）和唯一的长码掩码。共享的前向链路指示符信道用于向无线设备发送反向链路（RL）PC比特，例如使用TDM。数据通道由接收数据通道的所有无线设备共同供电控制。控制和指示器通道由每个无线设备单独进行功率控制，使得在这些信道上为无线设备发送的信令和RL PC位被可靠地接收。

摘要： In applications employing phase-shift keying modulation, a phase rotator as disclosed herein is used to rotate the constellation of signal vectors before carrier modulation in order to maximize modulator output power. Such a rotator may be applied in the digital domain (to complex signals having either binary-valued or multi-valued components) or in the analog domain.
