Large bandwidth is indispensable for future high-speed wireless transmission. However, implementation of traditional receiver demands ultra-high-speed ADC to receive large-bandwidth signals, which is challenging for current manufacturing. Motivated to defeat this challenge, we propose STTGR, which is literally extracted from stitching-together receiving. STTGR is a bandwidth extension receiving scheme...
This paper proposes an efficient phase-error suppression scheme for multiband (MB) orthogonal frequency-division multiplexing (OFDM)-based ultrawideband (UWB) communication systems. The proposed scheme consists of a clock-recovery loop and a common phase-error (CPE) tracking loop. The clock-recovery loop performs estimation of the sampling frequency offset (SFO) and its 2-D (time and frequency) compensation,...
