DPA: Delay Phased Array

Delay Phased Array - New programmable array with delays and phase shift to generate flexible frequency-dependent beams

We propose a new mmWave radio architecture called delay-phased
array (DPA) that improves efficient utilization of large bandwidth
and large antenna array at high mmWave frequencies by creating
flexible frequency-dependent multi-beams. DPA allows for flexible
division of system bandwidth into small bands and independent
radiation of each band in different chosen beam directions.

Requirements

• MATLAB software (tested with v9.14 or R2023a, but should work with other versions)
• Doesn't require any MATLAB toolbox.

Main code

• Run main_dpa.m to implement and plot a given flexible multi-beam pattern
• Play with parameters: Num antennas, system bandwidth, angles-per-beam, bandwidth-per-beam, number of beams etc
• Chnage other system parameters in lib_fsda/get_fsda_param.m
• Change algo_type to MATH to plot beam patterns computed through maths formula for delays and phase values
