Revision to the Proofs of: “Error Performance of Channel Coding in Random Access Communication”
The original proofs of Theorem 2 and Lemma 1 in the paper contain uncareful presentations that require further clarification. More specifically, the typicality thresholds used in the decoding algorithms should be functions of the codewords, since otherwise they may not be able to satisfy the formulas used in the proofs for their value determinations. The revised proofs are given below, and the ...
متن کاملChannel Coding in Random Access Communication over Compound Channels
Due to the short and bursty incoming messages, channel access activities in a wireless random access system are often fractional. The lack of frequent data support consequently makes it difficult for the receiver to estimate and track the time varying channel states with high precision. This paper investigates random multiple access communication over a compound wireless channel where channel r...
متن کاملRandom Access Channel Coding in the Finite Blocklength Regime
The paper considers a random multiple access channel communication scenario with an unknown number of transmitters. The collection of active transmitters remains fixed during each epoch, but neither the transmitters nor the receiver know which subset of transmitters that is nor even the number of active transmitters. The receiver discerns from the channel output both the number of active transm...
متن کاملcompensation of channel estimation error in tir-uwb communication systems
time reversal (tir) technique is an effective and simple method for data transmission in extremely multipath indoor uwb channels that mitigates the complexity of receiver by its own time focusing feature. although, tir method has the suitable performance, but it is sensitive to the non-ideal channel estimation error. in this paper at first, the bit error probability of tir-uwb communication sys...
متن کاملMixed Joint Source-Channel Coding Schemes for the Multiple-Access Relay Channel: Error Probability Analysis
In the following we denote random variables with upper case letters, e.g. X , Y , and their realizations with lower case letters , e.g. x, y. A discrete random variable X takes values in a set X . We use pX(x) to denote the probability mass function (p.m.f.) of a discrete RV X on X ; for brevity we may omit the subscript X when it is the uppercase version of the sample symbol x. We denote vecto...
