A Study on Gaussian Two-User Channels

Abstract

In this report, we study the Gaussian two-user channel which is an extension of an ordinary Gaussian channel with single input and output to the one with two inputs and two outputs and where the independent formations are transmitted between two input/output pairs simultaneously. Two achievable regions called TS and FDM1 are compared. TS is obtained by simply time-sharing the two superposition modes introduced in the previous paper and FDM1 corresponds to the frequency division multiplexing where only one of the two signals is transmitted in each of the two sub-bands. A fairly tight outer bound to the achievable region is obtained by utilizing the capacity region of the corresponding Gaussian broadcast channel. Properties of two kinds of frequency division multiplexing FDM2 and FDM3 which make use of the superposition modes are studied and the achievability attained by these two kinds of multiplexing is discussed using the results of computation.
