Diversity path signals, each comprising time division multiplexed symbols in a time slot including known symbols, are combined with respective weights to r educe co-channel interference. Initial weights are determined, using a window on t he known symbols, to optimize signal to interference plus noise ratio. These weights are used to determine symbols adjacent the window, and the window is changed to include determined symbols and the weights redetermined. This process is repeated wi th the window being moved progressively, preferably with successive positions overl apping, throughout the time slot. The initially known symbols can comprise synchroni zation symbols and/or CDVCC (coded digital verification colour code) symbols. Desir ably, both can be used with respective windows being moved in opposite directions throu gh symbols between them to provide two results for each such symbol, the better one of which is selected in dependence upon a monitoring of possibly averaged errors for the symbols.
