Hybrid Beamformer Codebook Design and Ordering for Compressive mmWave Channel Estimation
Junmo Sung, Brian L. Evans
In millimeter wave (mmWave) communication systems, beamforming with large antenna arrays is critical to overcome high path losses. Separating all-digital beamforming into analog an…
Versatile Compressive mmWave Hybrid Beamformer Codebook Design Framework
Junmo Sung, Brian L. Evans
Hybrid beamforming (HB) architectures are attractive for wireless communication systems with large antenna arrays because the analog beamforming stage can significantly reduce the…
ADC Bit Optimization for Spectrum- and Energy-Efficient Millimeter Wave Communications
Jinseok Choi, Junmo Sung, Brian L. Evans +1
A spectrum- and energy-efficient system is essential for millimeter wave communication systems that require large antenna arrays with power-demanding ADCs. We propose an ADC bit al…
Wideband Channel Estimation for Hybrid Beamforming Millimeter Wave Communication Systems with Low-Resolution ADCs
Junmo Sung, Jinseok Choi, Brian L. Evans
A potential tremendous spectrum resource makes millimeter wave (mmWave) communications a promising technology. High power consumption due to a large number of antennas and analog-t…
