Binary Search‐Based Division (BSBD): A Technique for Efficient Division in Hardware
Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.The division techniques play a key role in several computer‐implemented algorithms and applications; regrettably, they impose significant implementation constraints that hinder parallelization. The proposed binary search‐based division (BSBD) technique is inherited from the variable latency dividers, which have the potential to adjust the quotient bit ...

Power efficiency model for MIMO transmitters including memory polynomial digital predistortion [PDF]
, 2021 Multiple-input multiple-output (MIMO) beamforming array gain can make multi-antenna transmitters (TXs) more power efficient. However, these MIMO TXs require more complex digital predistortion (DPD).
