Abstract:
In one aspect, the present invention greatly simplifies soft modulation calculations, in part by exploiting certain properties of Gray-mapped QAM constellations used in modulating symbols of interest. In at least one embodiment, the simplified processing includes performing the soft modulation separately for the real and imaginary parts of each symbol of interest, by using the Gray mapping to decompose each of the real and imaginary parts into binary soft modulations for each bit. and then using a computationally-efficient table lookup to calculate the binary soft modulation. Here, the look-up table (32) comprises pre-computed bit contributions to the complex soft symbol value to be formed for the symbol of interest.

Abstract:
Teachings presented herein offer reduced computational complexity for detecting a plurality of symbol blocks, even for symbol blocks that comprise the combination of a relatively large number of symbols The teachings perform two or more stages of detection assistance to successively reduce the number of candidate combinations of symbols to be considered for a symbol block when detecting the plurality of symbol blocks. In particular, the teachings identify a reduced set of candidate symbol combinations for at least one symbol block m the plurality υf symbol blocks, and then jointly detect each of one or more distinct groups of symbols in the symbol block to determine from that reduced set a final reduced set of candidate symbol combinations. Detection of the plurality of symbol blocks limits the candidate combinations of symbols considered for a symbol block to the final reduced set of candidate symbol combinations identified for that symbol block.
Abstract:
Techniques for generating soft values for parity bits in a convolutional decoding process are disclosed. An exemplary method comprises, for each of at least one iteration m at least one soft-input soft-output decoder, calculating intermediate probability values for each possible transition between a first plurality of candidate decoder states at a first time and a second plurality of candidate decoder states at a second time. Two or more partial sums are then computed from the intermediate probability values, wherein the partial sums correspond to possible combinations of two or more systematic bits, two or more parity bits, or at least one systematic bit and at least one parity bit. Soft valuer, such as log-likelihood values, are then estimated for each of at least one systematic bit and at least one parity bit of the received Communications data corresponding to the interval between the first and second times. based on the partial sums

A base station is described herein that uses a root spreading code based code assignment to transmit signals to a mobile station. The mobile station can then suppress intra-block interference by effectively using a joint detection technique or a non- linear equalization technique to detect the transmitted symbols.

An electrical switch (100) comprising an actuator member (140) and a switching mechanism, the actuator member is movable between a first position and a second position corresponding respectively to on- and off- positions of said switching mechanism, the actuator member is arranged such that a two-stage movement is required to move the actuator member from the off- position to the on- position to operate said switching mechanism to mitigate risks of inadvertent actuation.
Abstract:
Teachings presented herein provide a method (100) and apparatus (10) for processing input information bits (16) for coding using a code (20), such that the length of the information word (14) formed from the input information bits (16) matches a fixed information word length defined by the code 20. In at least one embodiment, a coding circuit (10) receives input information bits (16) and adds error protection bits (26) as needed, to make the information word length match the fixed information word length. The method (100) and apparatus (10) contemplate generating the error protection bits (26) by sub-coding a subset (28) of the input information bits (26) (e.g., parity bit generation), thereby providing extra protection for that subset (28). These teachings allow the same code (20) to be used for coding feedback or other information, where the amount of information to be coded varies as a function of operating modes.
