Abstract

This paper evaluates the co-existence of a sensing information collection method, which collects the cooperative sensing information by using frequency based orthogonal narrow band signal overlaying to a primary system. In general, the cooperative sensing information is collected to a master node by using a different common channel with the primary system. However, the common channel decreases the channel efficiency and the secondary nodes have to prepare additional devices for sensing information collection. In this paper, we focus on the orthogonal frequency based sensing information collection method which can share the channel with primary system with small giving interference because the bandwidth of the signal is narrower than the primary system. We evaluate the performance of co-existence of the orthogonal frequency based sensing information collection method and a information collection method using whole band of the primary system without giving large interference to the primary system. From the computer simulation, we can confirm that the narrow band orthogonal frequency based sensing information collection method can expand the area of cooperative sensing with keeping the giving interference level to the certain level.
