1. A system comprising:
- a processing unit configured to (i) receive data signals as an input, (ii) remove effects of phase and amplitude distortions from the input, in order to produce reconstituted data signals, and (iii) provide the reconstituted data signals as an output; and
a transmitter electrically coupled to the processing unit and configured to receive and then wirelessly transmit the reconstituted data signals output from the processing unit.

Abstract
Provided is a system and method for removing the effects of phase and amplitude distortions from data signals having at least a third order signal level in a North American Digital Signal Hierarchy. The reconstituted signals are directly modulated onto a radio frequency carrier signal using phase shit keying modulation techniques and then wirelessly transmitted via a transmitter. Further, the wirelessly transmitted reconstituted data signals are received by a corresponding receiver using a squaring loop carrier recovery operation.

11. A system comprising:
-
first and second transceivers configured to cooperatively exchange data signals via a wireless communications link, each transceiver receiving a data signal during an exchange, wherein the exchange introduces phase and amplitude distortions in each received data signal; and
first and second processors electrically coupled to the first and second transceivers, each processor being respectively coupled to one of the first and second transceivers and configured to receive as an input the data signal received by the respective transceiver, wherein the first and second processors remove the phase and amplitude distortions from the data signal. - View Dependent Claims (12, 13)
