    摘要: There is disclosed a method and receiver for decoding a data signal from analogue signals received at one or more receiving antennas (24). The decoding is performed on the basis of bit value probabilities (66) derived from an effective signal to noise ratio (ESNR) (64) and a respective symbol error value (SEV) (62) calculated for all of the one or more receiving antennas. The ESNR is calculated utilising signal to noise ratios (SNRs) (58) per sub-channel and sub-channel transfer functions (60) measured for each of the one or more receiving antennas (24). Also, the SEVs are calculated utilising the measured sub-channel transfer functions.

    摘要: Nonzero elements of a signal vector, which may be a sparse signal vector, may be determined based on an observation vector representing a set of underdetermined observations using a compressed sensing optimization and a non-underdetermined estimation method such as iterative linear minimum mean-square error ("LMMSE") estimation. Compressed sensing optimization may be used to obtain a subset of potentially nonzero elements of the signal vector, and LMMSE estimation may then be used to find the nonzero elements among the potentially nonzero elements. The identification of nonzero elements may then be used to recover the signal vector from the observation vector. This technique is useful for recovering compressed data such as a sparse frequency space representation of audio or video data from a measurement. The technique is also useful for identifying at a base station a relatively small number of active devices in an overloaded communication network.

    摘要: One aspect of the present invention concerns the management of processing resource allocations for a Turbo receiver, where such resources are consumed from a finite resource budget within a defined processing time interval. The contemplated Turbo receiver attempts to allocate more processing resources to those demodulation and/or Turbo decoding tasks that make more valuable contributions with respect to the ultimate goal of successfully decoding all data streams that are of interest in a received signal. The advantageous management approach allows the Turbo receiver to obtain better results for a given consumption of processing resources, and further permits the Turbo receiver to quit upon either achieving a successful outcome within a defined processing time interval or exhausting the budgeted resources.

    摘要: Teachings presented herein offer improved symbol block detection by including a decoder unit in a demodulation system. Utilizing a decoder unit in a demodulation system can significantly enhance symbol block detection because the decoder can produce bit likelihood values (soft bit values), and these bit likelihood values can be used to construct a set of candidate symbol values. Advantageously, this set of candidate symbol values is more likely to contain the actually transmitted symbol(s) than if the decoder unit was not used in the demodulation system.
