| Abstract(in English) | Spectrum sensing technique must detect an extremely weak radio signal, and several techniques based on multiple receive antennas have been reported for the improvement of spectrum sensing performance. In general space diversity techniques, phase of signals obtained from each received antenna is arranged to combine these signals, however, because the amplitude of these signals is an extremely weak, it is difficult to detect the phase of these signals. On the other hands, the computational costs of the spectrum sensing increases in proportion to the number of receive antenna. Because the computational costs of the cyclostationarity detection based spectrum sensing are not small, the computational costs of the antenna diversity employed spectrum sensing must be reduced. Authors considered and reported some computationally efficient spectrum sensing techniques based on maximum cyclic autocorrelation selection using multiple receive antennas so far. These techniques combine the test statistics obtained from each receive antenna. In this paper, these computationally efficient spectrum sensing techniques are described. |
