摘要： A method for receiver processing in a 3GPP Long Term Evolution (LTE) receiver processing chain in a wireless mobile device is provided. LTE initial sub-frame transmitted from a base station is received on a LTE signalling channel. The sub-frame is received using a basic receiver. An integrity check is performed to determine if the sub-frame was demodulated and decoded correctly by the basic receiver. An advanced receiver is enabled prior to receiving an expected retransmission sub-frame based upon the integrity check failing and a hybrid-acknowledgement request (HARQ) negative acknowledgement (NAK) being sent by the wireless mobile device. The retransmission sub-frame is received using the advanced receiver. The basic receiver is enabled when the integrity check of the retransmission sub-frame passes and a acknowledgement (ACK) is by the wireless mobile device or a new data indicator (NDI) is set in a control channel indicating that the transmission is an initial transmission.

摘要： A method and device for performing forward error (FEC) correction avoidance based upon predicted block code reliability in a communications device is provided. An avoidance unit comprising a metric computation unit and a decision unit generates a reliability metric based upon a received code block. The reliability metric is compared to a reliability threshold, and the forward error correction decoder in the communications device is disabled if the metric is below or equal to the threshold.

摘要： A method for channel estimation includes receiving data at a number of frequency intervals in a frequency band over a number of first time intervals. A first set of channel estimates is determined (152) for each pilot symbol (106) within the data over a second time interval comprising at least one first time interval, and time-direction interpolation (154) is performed to determine a second set of channel estimates for a number of data portions in a frequency interval using the first set of channel estimates. The frequency interval comprises a data portion comprising a pilot symbol (106). Frequency-direction interpolation (156) is performed to determine a third set of channel estimates for each first time interval. The time-direction interpolation (154) and the frequency-direction interpolation (156) can be performed in reverse order with the channel estimates generated by the frequency-direction interpolation (156) being used as inputs for time-direction interpolation (154).

摘要： Method and a receiver in a communication system for receiving a transport block. The transport block comprises code blocks, each of the code blocks includes an error detection code and an error correction code. Reliability metrics are determined using an input generated during processing of the code blocks after the transport block is received. Each of the reliability metrics corresponds to each of the code blocks. A code block reorderer reorders the code blocks in an order based on the reliability metrics and a selection criterion. A decoder decodes each of the code blocks using the error correction code in the order. A verifier verifies each of the decoded code blocks using the error detection code.

摘要： Received point coordinates and estimated candidate coordinates are represented by a reduced bit representation, dividing each dimension into uniformly sized segments. A bounded region surrounding the received point is defined in the total number of dimensions, the bounded region being a hypercube. For each candidate, an elimination process is carried out including : determining whether the candidate is inside or outside the bounded region, eliminating the candidate if it is outside, storing it if it is inside, adding a further bit thereby reducing a size of the bounded region; repeating the elimination process for the candidates stored as potential solutions until a single solution is obtained; determining the transmitted symbols from the single solution found.
