Abstract:
1. In a base transceiver system of a wireless communication network, a method for transferring signal data from a radio frequency (RF) unit to a baseband processor over a serial data link, wherein the RF unit is connected to an antenna to receive an analog signal, the analog signal representing a plurality of antenna-carrier channels, the RF unit including an analog to digital converter (ADC) that converts the analog signal to a digital signal and a digital down converter (DDC) that downconverts the digital signal to a plurality of baseband channels, each baseband channel corresponding to one of the antenna-carrier channels and having a sequence of signal samples, wherein each signal sample includes an in-phase (I) sample and a quadrature (Q) sample, wherein the baseband processor performs signal processing operations on the signal samples received from the RF unit, the method comprising: compressing the signal samples of each baseband channel at the RF unit, wherein for each baseband channel the compressing comprises:
