Detection of occupied frequency bands is the foundation for applications of dynamic spectrum access (DSA). In order to convince network operators that DSA is feasible in cellular frequencies, it has to be shown that a reliable detection of their primary signals is possible. In this paper, we present the results of experimental validation of an algorithm and hardware, which can detect the presence of a Long Term Evolution signal. In contrast to the classical mono antenna approach, an array of antennas is used, which allows to enhance the detection capabilities, particularly when besides the useful signal there is also interference. |
