15 Gbps communication over an USB3.0 cable and even more

Parallel Sequence Spread Spectrum (PSSS) is a physical layer (PHY) base band technology. It was selected for the wireless sensor network standard IEEE802.15.4-2006 [1], because the data rate and performance were increased by PSSS. The main question to answer was during that USB3.0 project if PSSS could even enhance the communication over USB 3.0 cables. For the USB transmission a PSSS version with a different encoding then for IEEE802.15.4-2006 is used to enhance the data rate adapted to the spreading and cross talking of USB cables. Presented are the architecture of the whole test system, transceiver and offline processing model and the performance results.
