“…In the last decade, a significant growth in wireless cellular network has been observed [1,2]. However, the available technologies and the limited radio spectrum are unable to address the stringent demand for high data rate wireless communication [3][4][5]. It is desired to have a solution that can mitigate the problem of inadequate cellular spectrum [6].…”

Abstract-In this paper, we investigate the performance of a dual-hop block fading cognitive radio network with underlay spectrum sharing over independent but not necessarily identically distributed (i.n.i.d.) Nakagami-m fading channels. The primary network consists of a source and a destination. Depending on whether the secondary network which consists of two source nodes have a single relay for cooperation or multiple relays thereby employs opportunistic relay selection for cooperation and whether the two source nodes suffer from the primary users' (PU) interference, two cases are considered in this paper, which are referred to as Scenario (a) and Scenario (b), respectively. For the considered underlay spectrum sharing, the transmit power constraint of the proposed system is adjusted by interference limit on the primary network and the interference imposed by primary user (PU). The developed new analysis obtains new analytical results for the outage capacity (OC) and average symbol error probability (ASEP). In particular, for Scenario (a), tight lower bounds on the OC and ASEP of the secondary network are derived in closed-form. In addition, a closed from expression for the end-to-end OC of Scenario (a) is achieved. With regards to Scenario (b), a tight lower bound on the OC of the secondary network is derived in closed-form. All analytical results are corroborated using Monte Carlo simulation method.

“…MAC was first studied in [1] and [2] where the capacity region of the discrete memoryless MAC (DM-MAC) with independent sources was found. Many variations of the MAC have been studied, including the MAC with correlated sources [3]- [4], the MAC with feedback [5]- [9] and the MAC with side information [10]- [13], [17], [18]. In the case of the DM-MAC with feedback, Gaarder and Wolf [5] have shown through the use of a binary example that the capacity region of the DM-MAC can be increased using noiseless feedback from the receiver to both transmitters.…”

In this paper, we examine discrete memoryless Multiple Access Channels (DM-MACs) with feedback in the presence of two correlated channel states, each known to one encoder. Depending on feedback is two-sided or one-sided and also states are known to the transmitters non-causally or causally or strictly causally, we have six scenarios. Therefore, we present six achievable rate regions for these six scenarios by combining block Markov encoding, superposition coding and Gelf'and-Pinsker binning. We also show that our achievable rate region for the twosided feedback and non-causal states subsumes Cover-Leung's achievable rate region for the DM-MAC with two-sided feedback as its special case.

“…In this paper we derive the capacity region of the two-user Gaussian compound MAC with common message (GCMACC) and with ISI. The two-user compound MAC is a communication channel with two senders and two receivers in which two senders communicate with two receivers simultaneously and each of the two receivers need to decode all messages sent from both senders [6]- [9]. The capacity regions of the compound MAC with a common message and of compound MAC with conferencing encoders were established in [6].…”

In this paper, we characterize the capacity region for the two-user linear Gaussian compound Multiple Access Channel with common message (MACC) and with intersymbol interference (ISI) under an input power constraint. The region is obtained by converting the channel to its equivalent memoryless one by defining an n-block memoryless circular Gaussian compound MACC model and applying the discrete Fourier transform (DFT) to decompose the n-block channel into a set of independent parallel channels whose capacities can be found easily. Indeed, the capacity region of the original Gaussian compound MACC equals that of the n-block circular Gaussian compound MACC in the limit of infinite block length. Then by using the obtained capacity region, we derive the capacity region of the strong interference channel with common message and ISI. Keywords-Capacity region; compound multiple access channel; intersymbol interference (ISI); strong interference channelI.
