On Optimal Beam Steering Directions in Millimeter Wave Systems

Ahmed Elshafiy, Kenneth Rose, Ashwin Sampath

ICASSP 2019accepted

In order to increase system capacity and transmission rates, fifth-generation (5G) cellular and 802.11ad/ay wireless systems will use millimeter wave frequencies (24GHz-70GHz), which require large antenna arrays and narrow beamforming to mitigate the impact of substantial path-loss. While narrow bea…

On Error Resilient Design of Predictive Scalable Coding Systems

Ahmed Elshafiy, Tejaswi Nanjundaswamy, Sina Zamani, Kenneth Rose

ICASSP 2018accepted

Scalable coding is potentially useful in content distribution over unreliable channels, as it enables meaningful reconstruction when the hierarchical bitstream is only partially received. However, its deployment in conjunction with predictive coding may result in considerable performance degradation…
