Optimizing SDR performances on multi core processors: introducing the Cloud-SDR way

Extracting the sub-band of interest from a wide-band SDR device is a classical signal processing task and is the core of what SDRNode software is doing. This channelization process is exactly what your favorite SDR console program is doing: extract a tight band and demodulate it before sending it to your loudspeaker. There are several …
