Massive MIMO Reference Design
As part of the TitanMIMO-4 system, a reference design is provided which enables developers to rapidly implement Massive MIMO applications without dealing with drivers, data communications issues, data synchronization etc.
The provided reference design supports the data transfer, aggregation and control of all radio channels, from the radio nodes (RF Modules) through to the central baseband processing engine, and back to the radio nodes.
Record & Playback
Each 4×4 MIMO FPGA-based Perseus 6111 is equipped with a 4 GB SDRAM FPGA memory, which allows for recording of the full signal bandwidth, as shown in the calculation below:
- Four RF channels sampled at 61.44 MSPS.
- Each sample has 2 Bytes.
- Therefore 491.52 MBps are recorded to the SDRAM (4 x 61.44 MSPS x 2 Byte/Sample = 491.52 MBps).
The record/playback FPGA module provided with the system enables record or playback of the entire 100×100 system. 0.5 Giga-Samples per channel can be recorded to the SDRAM (4 GB divided by 4 channels divided by 2 Bytes per channel). This translates to a total recording of 8 seconds or a continuous playback for all 100×100 channels at full rate (61.44 MSPS).
