Abstract :
We approach additive white Gaussian noise (AWGN) multi-access channels from the perspective of studying the relationship among user specifications, and we establish an equivalence between a set of users with a certain characteristic and a single user. The consequence of this equivalence includes reduction of the complexity of achievability tests to between Ω(N) and O(N log(N)), a simpler and more insightful understanding that broadens the idea of successive decoding via user splitting, and other insights into such channels
