In this paper, we consider the possibility of utilizing the channel decoder output in the cancellation of multiuser interference. The paper contains a summary of our earlier numerical results followed by a discussion about some observations based on these simulations.

CDMA systems in multipath fading channels need to estimate channel parameters for coherent detection of the transmitted signals. In this paper we present a simple but effective channel estimation algorithm that can be incorporated into most types of multiuser receivers to obtain good detection performance. This technique uses a set of correlation filters to independently estimate each of the ch...

In code-division multiple-access systems, simultaneous multiuser accessing of a common channel is made possible by assigning a signature waveform to each user. Knowledge of these waveforms enables the receiver to demodulate the data streams of each user, upon observation of the sum of the transmitted signals, perturbed by additive noise. Under the assumptions of symbol-synchronous transmissions...

In this paper, we perform a cost-benefit analysis of multiuser diversity in single antenna broadcast channels. It is well known that multiuser diversity can be beneficial but there is a significant cost associated with acquiring instantaneous CSI. We perform a cost-benefit analysis of multiuser diversity for 2 types of CSI feedback methods, dedicated feedback and SNR dependent feedback, quantif...

Consider a channel allocation problem over a frequency-selective channel. There are K channels (frequency bands) and N users such that K = bN for some positive integer b. We want to allocate b channels (or resource blocks) to each user. Due to the nature of the frequency-selective channel, each user considers some channels to be better than others. Allocating each user only good channels will r...

This thesis represents an addition to the theory of information transmission, signal estimation, nonlinear filtering, and multiuser detection over channels with Gaussian noise. The work consists of two parts based on two problem settings—single-user and multiuser—which draw different techniques in their development. The first part considers canonical Gaussian channels with an input of arbitrary...
