DCSK (Differential Code Shift Keying)

The DCSK patented modulation technique (US patent #6,064,695) reaches superb reliability over noisy power lines. Implementation of DCSK in Yitran's IT800 ICs, provides a cost-effective robust solution for applications such as home automation, control and AMR (Automatic Meter Reading).

Traditional low speed PLC (Power Line Carrier) solutions illustrate the long standing demand for device control over power line, but have been severely limited by their throughput, reliability and scalability. Such solutions are not reliable enough for many of today's demanding PLC applications. Yitran’s patented technology significantly surpasses the performance of compatible modems at the same or lower total solution cost.

Competing power line modems, using other modulation techniques cannot reach the speed and reliability of DCSK, even through integration of DSPs and other expensive means.

Main Features and benefits:

• Close to theoretical reliability limits over Additive White Gaussian Noise (AWGN).
• Improved resistance to pulsed noise and narrow-band interference.
• Resistance to fast variations in line characteristics.
• Short synchronization time.
• Resistance to synchronization errors and timing jitter.
• Fast recovery from severe fade or jamming.

DCSK's inherent reliability can be further enhanced when combined with Yitran's proprietary Forward Short Block, Soft Decoded, Error Correcting code.
