ABSTRACT:
In a distribution telecommunications system, channel data for performing equalisation on a channel between a central station and an outstation is determined from measurements on pairs of pulses transmitted from the outstation. Each pulse pair comprises a first in-phase pulse and a second quadrature pulse having a predetermined time/phase separation. Coefficients for an active filter provided at the outstation are calculated from the multipath transmissions of the pulses and from the received time/phase separation of those pulses. The filter is then used to pre distort signals transmitted from the outstation.
