In this paper, we present a game theoretic framework for spectrum allocation in distributed cognitive radio networks containing both unicast and broadcast traffic. Our proposed scheme aims to minimize broadcast latency for broadcast traffic and minimize interference and access contention for both types of traffic. We develop a utility function that ensures(More)
In this letter, a virtual multiple-input single-output (VMISO) network employing non-coherent frequency shift keying (FSK) is considered. In the VMISO network, spatially separated single-antenna nodes transmit the same information cooperatively to a single receiver where each received signal is affected by an independent carrier frequency offset (CFO). The(More)
This paper presents an experimental comparison between cooperative communication and single-input single-output (SISO) system, in terms of the corresponding ranges of signal reception in each case. Transmissions have been achieved using Universal Software Radio Peripheral (USRP) platform, with the signal processing and time synchronization occurring in the(More)
—Millimeter wave communications rely on narrow-beam transmissions to cope with the strong signal attenuation at these frequencies, thus demanding precise beam alignment between transmitter and receiver. The communication overhead incurred to achieve beam alignment may become a severe impairment in mobile networks. This paper addresses the problem of(More)
This paper presents a comparison between cooperative networks with full relay participation and limited participation (LP), in terms of the energy used by the entire network and the bit error rate (BER) of the received signal. The Universal Software Radio Peripheral (USRP) platform was used to perform the transmissions while signal processing, combination(More)
