# 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](https://github.com/ucsdwcsng/dpa/blob/master/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](https://github.com/ucsdwcsng/dpa/blob/master/lib_fsda/get_fsda_param.m) - Change `algo_type` to `MATH` to plot beam patterns computed through maths formula for delays and phase values ## CIte our paper mmFlexible: Flexible Directional Frequency Multiplexing for Multi-user mmWave Networks [[pdf]](https://github.com/ucsdwcsng/dpa/blob/master/https://wcsng.ucsd.edu/files/mmflexible.pdf) Authors: Ish Kumar Jain, Rohith Reddy Vennam, Raghav Subbaraman, Dinesh Bharadia Infocom 2023
