Time sliding window for the detection of CCSK frames
Résumé
In wireless communications, frame detection and synchronization are usually performed using a preamble that consumes bandwidth and resources. A new type of frame called Quasi Cyclic Short Packet offers the advantage of avoiding preamble (thus saving resource) while allowing simple detection algorithm. The paper presents a time method to simplify the proposed detection algorithm and makes it robust to channel gain variation. First results show that a receiver can detect reliably short packet transmitted at few 100 Kbits/s at very low signalto-noise ratio (-10 dB, typically).
