Harmonized multi-RF band UWB-OFDM air interfaces for WPAN applications

This paper presents a multi-UWB-OFDM PHY layer system enable to operate in UWB spectrum mask and at 60 GHz considering two PHY layer systems ensuring a backward compatibility themselves. It allows large throughput scalability and frequency resource management. The system considers on the one hand enhanced baseband processing for ECMA-368 based on advanced binary interleaving techniques. The second one is an optimized UWB-OFDM system based on spectrum efficiency optimization combined with advanced interleaving techniques. Advanced interleaving techniques resort from time-variant binary block interleaving codes denoted Dynamic Binary Interleaving Code (DBIC) considered here as an alternative to the ECMA-368 standard binary cyclic shifter stage and H/W complexity reduction issues. DBIC is designed and assessed on multi-UWB-OFDM PHY layer system. DBIC is implemented thanks a recent interleaving technique denoted Turbo-Like Interleaver (TLI) allowing multiple interleaving pattern generation into a flexible way. This work has been realized within the framework of the ICT-FP7 OMEGA project.
