  • Abstract
    This paper presents the hardware architecture and the corresponding implementation details of a configurable and optimized FPGA-based time-domain frequency shifter with application to Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) systems. The architecture is mainly based on a customized Numerically Controlled Oscillator (NCO) that is used for generating complex exponentials employing only adders, a Look-Up Table (LUT) and plain logic resources.
