Asynchronous multiple-access channel capacity
The capacity region for the discrete memoryless multipleaccess channel without time synchronization at the transmitters and receivers is shown to be the same as the known capacity region for the ordinary multiple-access channel. The proof utilizes time sharing of two optimal codes for the ordinary multiple-access channel and uses maximum likeliiood decoding over shifts of the hypothesized trans...
متن کاملAnalysis of Collision Channel with Asynchronous Access
SUMMARY A T user multiple access collision channel without feedback is considered where the channel inputs are called packets. The packets take values from non-binary input alphabet. It is supposed that at most M users are active, i.e., are communicating simultaneously (2 ≤ M T). We are looking for codes and protocol sequences of users of minimum length such that from the output of the channel ...
متن کاملInterleaver-Division Multiple Access on the OR Multiple Access Channel
The OR channel provides an unusual opportunity where single-user decoding permits operation at about 70% of the full multiple-access channel sum capacity. The interleaverdivision multiple access technique applied in this paper can approach that performance with turbo and LDPC solutions. The current paper focuses on very low latency codes with simple Viterbi decoding, intended for very high spee...
متن کاملMultiple Access Channel with Feedback
Multiple access channel with feedback is an extension of classical MAC, by providing senders with ability to observe the channel output. The capacity region in the general case is not known. This report presents the main results of [1] by Cover and Leung, which is a region of achievable rates exceeding the capacity region of classical MAC (section 3). Since the coding technique used in [1] reli...
متن کاملBounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel
In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
