Physical layer design for mm-wave WPANs using adaptive coded OFDM

The mm-wave band (typically 59-64 GHz) has attracted a lot of attention in recent years for use with wireless personal area networks (WPANs), and is the subject of a major ongoing standardisation effort [1]. This paper considers the design and simulation of a possible physical layer (PHY) solution for mm-wave WPANs using an adaptive orthogonal frequency division multiplexing (OFDM) scheme with low density parity check (LDPC) coding. Particular focus is given to the proposed frame structure, methods for synchronisation, channel estimation, and tracking/compensation of common phase error. Additionally, a robust "startup" mode is described for use in signalling the medium access control (MAC) allocations and the PHY adaptation parameters. It is demonstrated by way of simulation that the proposed scheme is capable of achieving information rates typically above 500 Mbits/sec even for non-line- of-sight (NLOS) scenarios when a ceiling mounted access point is employed for a large office scenario.
