Abstract:

Digital-intensive RI; transmitters using delta-sigma modulation have a compact physical footprint, enabling a low-cost mobile MIMO transmitter for 5G systems, but suffer from a high noise floor due to quantization errors. In order to eliminate the need of high-Q multi-band RP filters for attenuating such high noise floor, this paper for t...More
