“…Note that by splitting the message M 2 to two sub-messages and letting M 2c be decoded at the first decoder, receiver 1 is able to reduce the effective interference and therefore, the rate R 1 is boosted. Finally, the rate region R ZIC-NSI is achieved by joint typicality decoding [11].…”

“…Proof: The proof follows the same lines as that of Theorem 1 except that in this case, since V 1 , V 2 are independent of S 1 , S 2 , the encoding scheme does not include binning and during the codebook generation process, instead of generating 2 n R k +R k , k = 1, 2, n-sequences v n k , we only generate 2 nR k such sequences. Therefore, by negligibly altering the codebook generated we can easily derive the expressions in (17). In fact, if the senders want to send (m 1b , m 2b ) to the receiver, upon choosing the helping index m 0b , they find the suitable u n , v n 1 and v n 2 sequences directly and then send x n 1 and x n 2 where…”

“…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.

“…Simeone et al [7] extended the channel models in [6] to the case with conferencing decoders and studied the compound MAC with a common message and conferencing decoders, and compound MAC with both conferencing encoders and decoders. Recently, the compound MACC with Slepian-Wolf type correlated channel states has been studied in [8].…”

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.
