dMASS — Distributed Massive MIMO SDR Platform
dMASS is a scalable distributed SDR platform built around synchronized dSDR direct-sampling radio modules for high-channel-count RF infrastructure, geolocation, distributed sensing, and massive MIMO systems.
The platform combines phase-coherent synchronization, FPGA-accelerated processing, PCIe Gen3 transport, and optional 100GbE networking into a deployable SDR infrastructure architecture optimized for distributed RF acquisition and real-time signal processing applications.
A single dMASS system supports up to four synchronized dSDR-1K50 modules, enabling scalable deployments with up to 24 RX and 16 TX coherent channels.
Why dMASS
dMASS extends the dSDR platform into scalable distributed RF infrastructure with synchronized multi-node acquisition, high-throughput transport, and phase-coherent operation for geolocation, massive MIMO, and distributed sensing systems. The architecture enables deterministic synchronization across M.2 2242 SDR nodes while supporting scalable RF acquisition, FPGA-accelerated processing, and real-time infrastructure deployment.
