This paper presents the design and test of 2×2 channel emulator, which is especially optimized for LTE-Hi testing. It adopts traditional convention method of the channel impulse response in time domain. The design features lower memory resource with sharing delay data buffering, which could reduce the cost of efficient VLSI Implement. In addition, Bidirectional design offers flexible and reliable...
A transceiver with adaptive power control using a process and frequency monitor (PFM) is proposed. The PFM employs gain calibration with a replica voltage-controlled oscillator (VCO) and operates in the background. A five-bit digital code detected by the VCO gain calibration is applied to an adaptive-amplitude driver, an adaptive-bandwidth receiver, and an adaptive-bandwidth phase-locked loop. A test...
