DSP Design and Implementation for the UE Modem Controller of the 3G Long-Term Evolution

Abstract

The 3G LTE will provide the increased data rates, improved coverage, improved spectrum efficiency and reduced latency with adapting various transmission parameters for high-speed data transmission. Accordingly, we suggest an efficient method for controlling FPGAs in the user equipment of the 3G LTE. Our proposed DSP software design, the UE Modem Controller, reduces processing latency for controlling modem hardware since it has been designed as interrupt service routines based on its functions and FPGAspsila operation timing. Furthermore, it performs complex computations required in FPGAs and store various physical parameters to control UE modem at the right time.
