摘要： An apparatus and method for canceling interference in an OFDM system using multiple antennas, where based on error estimation of a symbol received from a receive antenna, the error of a symbol received from another receive antenna is estimated. Prior to transmission, symbols to be transmitted through a plurality of transmit antennas are shifted by a predetermined number of bits without overlapping. Thus, the effects of an error of a symbol received from a receive antenna on error estimation of a symbol received from another receive antenna are reduced.
摘要翻译：使用多个天线来消除OFDM系统中的干扰的装置和方法，其中基于从接收天线接收到的符号的误差估计，估计从另一个接收天线接收的符号的误差。在发送之前，要通过多个发送天线发送的符号被移位预定数量的比特而不重叠。因此，从接收天线接收的符号的误差对从另一接收天线接收的符号的误差估计的影响减小。

摘要： A receiving apparatus and method for receiving signals through a plurality of receive antennas in a mobile communication system. In the receiving apparatus, a plurality of FFTs transform frequency-domain symbol sequences received from the receive antennas to time-domain FFT symbol sequences, an SIC receiver decides the value of a higher-priority transmitted symbol sequence using its FFT symbol sequence and decides the value of a lower-priority transmitted symbol sequence using the decided higher-priority transmitted symbol sequence and its error, a plurality of demodulators demodulate the decided transmitted symbol sequences to a plurality of coded bit streams, a plurality of deinterleavers deinterleave the coded bit streams, stream by stream, and a parallel-to-serial converter converts the deinterleaved coded bit streams to one coded bit stream.

摘要： Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use either a single antenna mode or a multiple antenna mode such as a dual antenna mode in monitoring the paging channel. In the single antenna mode, a single active antenna is used to receive paging signals. In the dual antenna mode two antennas are simultaneously used to receive paging signals. The device may choose which antenna mode to use based on signal quality measurements and history information on successfully received paging signals.

摘要： A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.
摘要翻译：用户设备从基站接收分组。基于给定分组的不完整内容，用户设备可以在分组仍在接收时调用解码。这种“部分分组解码”依赖于以冗余（代码率小于1）对分组中的底层信息进行编码的事实。如果链路质量差，则部分分组解码可能不成功，即在尝试恢复基础信息时失败。为了避免浪费电力，用户设备可以被配置为在对当前分组调用部分分组解码之前应用一个或多个链路质量测试。

摘要： A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.

摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use a selected one of the multiple antennas in monitoring the paging channel. If received signal quality is satisfactory, the device may maintain use of the selected one of the multiple antennas for subsequent wake period monitoring of the paging channel. If received signal quality falls below a threshold or is otherwise indicated to not be satisfactory, the device may switch to use of a different one of the multiple antennas in monitoring the paging channel. Other criteria may also be used in controlling the switching between antennas for paging channel monitoring.
