Abstract
In this paper, a novel comprehensive transmitter architecture has been proposed, which enables the concurrent transmission of two separate frequency bands by carrier aggregation. For different frequencies, the proposed transmitter can simultaneously employ 1-bit Low-pass and Band-pass delta-sigma modulators structures, or employ hybrid structures. Carrier frequencies are equal to oversampling frequencies of modulators. Besides, signals on two carriers are not interfered with each other to ensure transmission dual-band signal. Performance analysis is simulated by using Matlab/Simulink. The simulation results achieve high signal-to-noise radio and show the effectiveness of the proposed architecture.
