Abstract:
1. In a base station wideband transceiver capable of operating in a wireless cellular communications system that communicates with mobile subscribers, a method for equalization in transmit and receive levels, comprising the steps of: assigning a plurality of transmit and receive carrier frequencies to the base station wideband transceiver; flattening a spectral response of said base station transceiver across a range of frequencies including the plurality of transmit and receive carrier frequencies using software amplitude pre-distortion; wherein the method further comprises the step of making narrowband IF channel measurements using an automated broadband radio frequency transceiver test (ABRFTT) to determine a set of coefficients for each narrowband IF channel; wherein the ABRFTT further comprises the step of making wideband RF channel measurements that step through the wideband bandwidth to determine a set of coefficients for the wideband RF channel; wherein the ABRFTT creates 25 narrowband coefficients for a 5 MHz IF bandwidth and 300 wideband coefficients for a 60 MHz RF bandwidth having 200 kHz channels.
