Experimental Study of 3G Signal Interaction in Nonlinear Downlink RAN Transmitters

While RF communication signal distortions in nonlinear transmission paths have been predicted theoretically and studied experimentally for various signals, it is interesting to examine a wideband nonlinear system reaction to a wideband 3G signal and a narrowband 2G signal. Research and testing have demonstrated that, while most vital signal parameters remain within the limits specified by applicable standards even if composite signal power approaches specified maximum power, a relatively high level of spurious emissions caused by cross- and intermodulation can result. To avoid degrading both existing and new systems, this and other signal quality issues must be considered when designing and deploying multitechnology systems.
