摘要： A Viterbi decoding device to decode a signal produced by a convolutional encoder is described. The device may include: an analog-to-digital conversion unit to extract a soft symbol S=(S0, S1) from the signal, the soft symbol including a first sample value S0 and a second sample value S1; and a digital processing unit to compute, for each of the N states, a branch metric value of BM—0_K in dependence on the soft symbol S, K being an index identifying the respective state. The digital processing unit may store the soft symbol S as a complex number S=S0+J*S1 in a complex number format; and compute a complex branch metric value BM—0_(K, K′)=BM—0_K+J*BM—0_K′ in a complex number format on the basis of the soft symbol S, with K different from K′.

摘要： A convolutional encoder may have N different states, each having two predecessor states, each branch from each of the two predecessor states having a static code word CW=(B0, B1) and produces a signal having a sequence of the code words. A Viterbi decoding device includes an analog-to-digital conversion unit arranged to extract a soft symbol S=(S1, S2) from the signal; and a digital processing unit connected to the analog-to-digital conversion unit and arranged to compute, for each of the N states, a branch metric value BM_0_K in dependence on the soft symbol S, K being an index identifying the respective state. The digital processing unit may store the soft symbol S as a complex number; and compute a complex branch metric value BM_0_(K, K′)=BM_0_K+J*BM_0_K′ in a complex number format on the basis of the soft symbol S, with K different from K′.

摘要： A processor unit used to determine a quality indicator, QI, of a communication channel. The processor unit receives received complex symbols at an input, executes a predetermined sequence of transformations on the received complex symbols and computes the error vector magnitude, EVM. The quality indicator, QI, of the communication channel is determined based on the determined error vector magnitude, EVM. Data representing the quality indicator, QI, is outputted at an output of the processor unit. The predetermined sequence of transformations transfers all the received complex symbols to a single predetermined region containing a single target location. The error vector magnitude, EVM, is then calculated as average distance of all the processed received complex symbols in the predetermined single region to the single target location.
