Come tradurreste "code mapper scheme"?

"It has been found that this inherent quantisation limit is almost exactly the same for embodiments explored by simulation as for a prior art code mapper scheme operating under the same conditions in terms of the sample rate, chip rate and reference sequence duration in chips), where both are simulated in a noiseless environment."


Qui compare tre volte:

"As noise is added to the simulations, and the signal to noise ratio (SNR) is reduced to realistic levels, the two schemes remain equivalent provided that the prior art code mapper and its associated correlator process all the input samples. Embodiments of the invention that employ a matched filtering approach always exploit all the input samples. If a code mapper scheme is implemented which processes only a subset of input samples then its SNR gain and hence performance falls. This can be appreciated by noting that processing fewer than all the samples caused noise to be aliased in. In practice, known prior art code mapper schemes always process samples at too low a rate to achieve optimum SNR. In contrast, the matched filtering approach as used in embodiments of the present invention always exploit all of the input samples."
