Abstract
The invention provides radio communications with an up-down signal link. In accordance with the purpose of the invention, as embodied and broadly described herein, the invention is directed to a method, system and computer readable medium with program instructions (hereafter collectively referred to as 'the invention'). The invention includes receiving a downstream signal in a receiver portion of an outdoor unit, producing in the receiver portion of the outdoor unit an intermediate frequency (IF) signal from the downstream signal, and processing the IF signal in the receiver portion of the outdoor unit to produce a clean line code signal. The invention further includes processing the clean line code signal in the receiver portion of the outdoor unit to produce a modulated signal, and providing the modulated signal via an interface portion of the down-link to an indoor unit, wherein the producing and processing, respectively, of the IF, clean line code and modulated signals in the outdoor unit provides a high, constant signal-to-noise ratio on the down-link, and wherein the modulated signal is converted to a binary signal in the indoor unit. The invention additionally includes providing an upstream signal over an up-link to a transmitter portion of the outdoor unit, and selecting a component of the upstream signal for transmission by the outdoor unit. One aspect of the invention also includes measuring in the receiver portion of the outdoor unit a power level of the received downstream signal, wherein the measured power level is unaffected by characteristics of the down-link. Moreover, the invention includes providing loop-back connections in the indoor and outdoor units for automated testing of the indoor and outdoor units.
