Progress is also discussed in our developer meetings. See OpenAirDevMeetingsfor more details.
The processing requirements for 5G-NR are much higher as for 4G, so a high end PC or server is needed. So far we have been using
Intel Core i7 6900K (8 cores), 16GB DDR, 480GB SSD (~2200€).
Allows SW LDPC on 3 cores (1 segment per slot, 3 slots decoded in parallel, up to 30Mb/s) or LDPC on FPGA (up to 300Mb/s on 80MHz SISO).
Intel Core i9 7980EX (18 cores) shall support future configurations incl. MIMO (~3700 €).
Allows parallel LDPC SW decoder on 9 or 12 cores, up to 3 (tested) or 5 (ongoing) segments per slot or 140Mb/s or LDPC on FPGA (same as above)
Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz with 18 cores and 2x10Gbit Ethernet
This older platform will also work with 5G-NR, but only supports bandwidths up to 80MHz with 3/4 sampling.
This platform can be used for bandwidths up to 40MHz using 3/4 sampling.
The SYRTEM platform is based on the Xilinx EVALUATION KIT ZYNQ-7000 ZC706 (ex. supplier Digikey ref: 122-1904-ND, 2427€)
and the Analog Device Transceiver type ADRV9371 (ex. supplier : Digikey ADRV9371-W/PCBZ-ND ('WIDE TUNING RANGE 300MHZ-6HGZ' version) 1169€).
As a high performance alternative to the software LDPC decoder included in this release, the decoder can also be offloaded to another FPGA board (EVALUATION KIT ZYNQ-7000 ZC706).
