| Abstract(in English) | The signal-to-noise ratios (STRs) and the bit error rates (BERs) of K signals recovered by the Independent Component Analysis (ICA), namely passed through the ICA filter, are calculated numerically and analytically. It is found that these quantities with the ICA filter are much larger than those of the original signals although the waveforms of the signals passed through the ICA filter are almost the same as those of the original signals. Using this effect, we can generate much more useful speading sequences. The chip-synchronous systems using the spreading sequences passed through the ICA filter have the same BERs as the Walsh-Hadamard sequences. Furthermore these sequences can be generated with any code length. |
