Abstract
In mobile radio communications systems using time-division multiple access (TDMA), intersymbol interference caused by time differences in multipath media is avoided by equalizing data blocks. When a data block (BD) is received, the impulse response of the channel on which the block was transmitted is estimated, a set of receive parameters (PP) is evaluated, an optimal length (Nopt) of the block (BD) is determined from the parameters (PP), and when the optimal length (Nopt) is less than the actual length (N) of the block (BD), channel variation tracking (PO) is undertaken.
