Thereafter, the controller generates a reference signal based on the information representative of the selected QPSK sequence.

Abstract: Receiving units will switch between performing a DC bias suppression and not removing the DC distortion at the receiver depending on the amount of DC interference level observed/measured/estimated. Since the overall DC interference is from all uplink transmitters, potentially at different power levels, the amount of DC distortion can be measured based on the difference between the received power level and the expected power level on the DC sub-carrier. Additionally it can be estimated based on the number of active transmitters, their allocation bandwidth, power control target and/or a rough estimate of the DC distortion introduced by each active transmitter and also the distortion introduced by the receiver. Once this distortion level is estimated, a decision is then made whether or not to remove the DC distortion.

Abstract: Communications sourced by a remote unit (14) that is already within reception range of a base site (10) can nevertheless be further facilitated through allocation of one or more relay resources (15, 16). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.
