Single-antenna co-channel interference cancellation for TDMA cellular radio systems

Co-channel interference cancellation is particularly challenging in the downlink of cellular radio systems because usually only one receive antenna is available at the mobile terminal. This tutorial provides an overview of promising a single-antenna co-channel interference cancellation techniques. Focus is on the downlink of time-division multiple access systems. The results may, however, be extended to related applications, including interference suppression in multiple-input multiple-output systems.

Single antenna interference cancellation (SAIC) for cellular TDMA networks by means of joint delayed-decision feedback sequence estimation

In this letter, single antenna co-channel interference cancellation for cellular time-division multiple access (TDMA) networks by means of joint delayed-decision feedback sequence estimation is studied. The performance is increased by a novel adaptive state allocation technique

Joint delayed-decision feedback sequence estimation with adaptive state allocation

Single antenna co-channel interference cancellation for cellular TDMA networks by means of joint delayed-decision feedback sequence estimation is proposed. The performance can be increased by a novel adaptive state allocation technique.

Impulse response shortening for multiple co-channels

In this paper, a novel design of a receiver-side FIR prefilter is proposed which is able to jointly shorten the impulse responses of multiple co-channels given just one receive antenna. The prefilter coefficients are computed without explicitly solving an eigenvalue problem. In conjunction with a reduced-complexity multiuser detector, a good error performance can be achieved. As a possible application, co-channel interference cancellation for the EDGE system is studied. The prefilter, however, is also suitable for interference suppression in MIMO systems, for crosstalk suppression, or for reducing the length of the cyclic prefix in multitone systems, among other applications.
