 # Overview
-This is a customizable synthesizable 5G NR lower PHY written in Verilog intended to be used in a UE (user equipment). It can run on an [AntSDR e310]([https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html](https://de.aliexpress.com/item/1005003181244737.html)), which has a Xilinx® Zynq Z-7020 with only 220 DSP slices and 85K logic cells, at 7.68 MSPS (512-FFT), 15.36 MSPS (1024-FFT) is probably also possible but not yet tested. In this configuration 25 PRBs (physical ressource blocks) can be used, which results in a so called '5 MHz' 5G channel (the usable bandwidth is actually 4.5 MHz) which could be made 5G-NR RedCap compliant.

In this 5 MHz configuration, 25 PRBs (physical ressource blocks) can be used. This will become a 5G NR standard compliant mode once 5G-NR RedCap will get standardized.

 Cell search is limited to 1 frequency offset range. Within this frequency offset range, the PSS correlator works up to a CFO of about += 10 kHz.
 Each PSS correlator detects one of the possible three different PSS sequences. If a general cell search for all 3 possible N_id_2's is needed, 3 PSS correlators need to be instanciated in parallel. If CFOs larger than the detection range of the PSS correlator are expected, the different CFO possibilities can be tried sequentially by configuring the receiver via its AXI-lite interface.
