摘要： A method for using a joint decoding engine in a wireless device is disclosed. A first symbol stream and a second symbol stream in a received multiple input multiple output (MIMO) signal is determined. A scaled channel estimate for a wireless transmission channel and a scaled noise covariance of the MIMO signal are also determined. The scaled channel estimate and the first symbol stream are whitened. Max log maximum a posteriori (MLM) processing is performed on the whitened first symbol stream to produce a first data stream. The first data stream may be de-rate matched and decoded to produce a decoded first data stream.

摘要： Providing for reduced complexity or improved accuracy in de-mapping received wireless data streams for multi-channel wireless communication is described herein. By way of example, a low-complexity likelihood algorithm can be employed to de-map data bits from the wireless data streams. In one particular example, the likelihood algorithm can approximate a received bit with a subset of received wireless symbols correlated the bit, reducing algorithm complexity. In other examples, a limited set of received wireless symbols can be employed for the subset, further reducing algorithm complexity. According to at least one other example, logarithmic terms of the algorithm can be approximated with non-logarithmic functions, such as a look-up table, series expansion, polynomial approximation, or the like. These approximations can enhance symbol de-mapping accuracy while maintaining or improving processing overhead for a wireless receiver.
摘要翻译：在此描述了针对用于多信道无线通信的接收到的无线数据流进行解映射时降低的复杂度或改进的准确度。举例来说，可以采用低复杂度似然算法来从无线数据流中解映射数据比特。在一个特定示例中，似然算法可以用接收到的与该位相关的无线符号的子集来近似接收的位，从而降低算法复杂度。在其他示例中，可以为该子集采用有限组的接收无线符号，从而进一步降低算法复杂度。根据至少一个其他示例，算法的对数项可以用诸如查找表，序列扩展，多项式近似等的非对数函数近似。这些近似值可以增强符号解映射的准确性，同时保持或改善无线接收器的处理开销。

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform calibration of a transceiver chain to maintain or improve operation of a device or comply with legal or protocol requirements. The UE may receive one or more wireless signals indicating a first set of resources where the first device is scheduled to transmit or receive communications. The UE may calibrate a wireless transceiver chain of the first device in a second set of resources. The second set of resources excludes the first set of resources and includes at least a portion of a third set of resources. The third set of resources are resource in which the first device has an option to transmit or receive communications based on a protocol configuration.

摘要： Methods and devices are disclosed for enabling improved performance on a multi-subscriber identification module (multi-SIM) wireless communication device. The wireless communication device may detect transmit activity on a modem stack associated with the first SIM, and detect a communication activity scheduled on a modem stack associated with the second SIM having a higher priority. If the transmit activity on the modem stack of the first SIM will impede the communication activity, the wireless device may identify subframes on the modem stack associated with the first SIM that overlap in time with the communication activity and for each identified subframe, blank symbols that conflict with the communication activity to develop a partially blanked subframe. The partially blanked subframe may be transmitted according to a blanking policy.

摘要： A method and apparatus for decoding of tailbiting convolutional codes (TBCC) are disclosed. The proposed modified maximum-likelihood TBCC decoding technique preserves error correction performance of optimal maximum-likelihood based TBCC decoding, while the computational complexity is substantially decreased since a reduced number of decoding states has been evaluated. Compare to other sub-optimal TBCC decoding algorithms, modified maximum-likelihood TBCC decoding achieves improved packet error rate performance with similar computational complexity.
