Abstract: Wireless transceiver apparatus is described for operating in a part of the RF spectrum in which a first wireless transceiver apparatus shares with a co-located second wireless transceiver apparatus.
The first wireless transceiver apparatus comprises:
a wireless transceiver unit;
an arbitration interface for interfacing with an arbitration entity which arbitrates access to the shared part of the RF spectrum between the first wireless transceiver apparatus and the second wireless transceiver apparatus;

wherein the arbitration interface is adapted to signal time periods when the wireless transceiver unit is operational, or requests to be operational;
and wherein the arbitration interface is adapted to signal data about the first wireless transceiver apparatus during other time periods.

Abstract: A signal resampler carries out a time domain interpolation of an input signal for compensating for frequency offset, such as found in an ADSL system. A sample selector interpolator carries out part of the interpolation and a second, e.g. polynomial interpolator carries out the rest of the interpolation. The time interval between samples being interpolated, can be effectively divided between sample selector interpolator and a small second, e.g. polynomial interpolator. The complexity of the second, e.g. polynomial interpolator can be reduced or its accuracy increased if it is effectively interpolating over a much smaller time interval. The sample selector interpolator can be an oversampling arrangement, and enable the order of the second, e.g. polynomial interpolator to be reduced. Selected ones of the oversampled samples are fed to the second, e.g. polynomial interpolator to keep the operating frequency lower. A chain of upsamplers can be used to generate the oversampled samples.
