Abstract
An overview of methods currently proposed for the equalization of in-service high-speed TDMA satellite channels is provided. Three classes of techniques are identified and are (in order of decreasing cost and complexity): adaptive nonlinear equalization, linear adaptive transversal equalization and equalization by manually adjustable equalizers that are periodically adjusted using the amplitude and phase response of the channel derived from a burst mode link analyzer (BMLA). Particular attention is given to the least squares impulse response estimation (LSIRE) BMLA, which offers encouraging potential as a cost effective, software intensive method of monitoring high speed TDMA channels for the purpose of equalization. A report is given of simulated results for the LSIRE BMLA. In particular the performance of such a BMLA as a function of the traffic signal sampling resolution is presented.
