This paper presents a cyclic autocorrelation function (CAF) diversity combining technique for spectrum sensing using test statistics shared among multiple receive antennas with time-averaged weights. We recently reported a weighted CAF diversity combining technique, however, the weight factor has a noise component, which negatively affects the performance. This technique reduces the noise component...
This paper presents a feature detection based spectrum sensing technique by some test statistics sharing among multiple receive antennas. In conventional feature (signal cyclostationarity) detection based spectrum sensing techniques with multiple antenna systems, computational complexity is not low, and it increases in proportion to the number of receive antennas. In this paper, test statistics are...
This paper presents a weighted diversity combining technique for the cyclostationarity detection based spectrum sensing of orthogonal frequency division multiplexing signals in cognitive radio. In cognitive radio systems, secondary users must detect a desired signal in an extremely low SNR environment. In such environments, multiple antenna techniques (space diversity) such as a maximum ratio combining...
