In frequency division duplex systems, it is extremely difficult to position the receiver (Rx) that belongs to another system, defined as the third-party Rx, because the sensors usually do not know which band the Rx uses for reverse transmission. In this letter, we propose a new method to position the third-party Rx based on the transmitted signal of the third-party transmitter (Tx). In particular,...
Even though the wireless positioning in sensor networks has been extensively studied in the past decades, there is no contribution discussing positioning the receiver that belongs to another system, i.e., the third-party receiver. In this paper, we propose a new scheme to solve the problem by full-duplex rtechnique. In our scheme, we let the sensors conduct the full-duplex relay for the target receiver...
Cooperative spectrum sensing improves detection performance over fading and shadowing channels by using multiple cognitive radio (CR) users. Compared with local spectrum sensing with individual CR user, it can either reduce sensitivity requirements for each CR user or shorten the overall sensing duration. These advantages are from spatial diversity when all cooperative users sense a common primary...
