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 کاملThe capacity region of the symbol-asynchronous Gaussian multiple-access channel
Akhsrract --In the information theory of the multiple-access channel, two types of synchronism are usually assumed among the transmitters, namely, frame and symbol synchronism. Frame synchronism refers to the ability of the users to start the transmission of their codewords in unison. The issue of symbol synchronism arises in continuous-time channels in which each codeword symbol modulates a fi...
متن کاملClassical Capacity of A Quantum Multiple Access Channel
In quantum information theory, a basic question often presented is how efficiently can one transmit classical information over a quantum channel.[1, 2, 3] Because of the non-orthogonality of quantum states, the channel capacity is different from that of the classical channel discussed in [4, 5] . Recently, this question has attracted new attention due to the rapid progress in quantum informatio...
متن کاملOn the Capacity Region of Multiple Access Channel
The capacity region of a multiple access channel is discussed. It was found that orthogonal multiple access and non orthogonal multiple access have the same capacity region under the constraint of same sum power.
متن کاملThe capacity of the quantum multiple-access channel
We define classical–quantum multiway channels for transmission of classical information, after recent work by Allahverdyan and Saakian. Bounds on the capacity region are derived in a uniform way, which are analogous to the classically known ones, simply replacing Shannon entropy with von Neumann entropy. For the single receiver case (multiple access channel) the exact capacity region is determi...
