Such antenna array-based receivers employ digital signal processing backends\, often im plemented on field programmable gate array (FPGA) based platforms to produ ce multi-beam array response patterns. This talk presents recent research findings incorporating approximate trigonometric transforms in conjunction with approximate computing units on FPGAs to provide low complexity DSP b ack-ends for multi-beamforming arrays. The presentation will show how appr oximations can be employed at both algorithmic and computing levels to sig nificantly reduce the hardware complexity while maintaining acceptable bea mforming performance.\n\nSpeaker(s): Chamith Wijenayake\, \n\nVirtual: htt ps://events.vtools.ieee.org/m/570065 LOCATION:Virtual: https://events.vtools.ieee.org/m/570065 ORGANIZER:thiaza.thasthakeer@gmail.com SEQUENCE:34 SUMMARY:Low-Complexity Digital Multi-Beamforming Using Approximate Computin g URL;VALUE=URI:https://events.vtools.ieee.org/m/570065 X-ALT-DESC:Description: <br /><p>Digital multi-beamforming is a crucial req uirement in modern wireless communication\, navigation\, and radar applica tions\, where highly directional communication is enabled through antenna arrays.
