Invited presentation 1: Air Interface and Physical Layer techniques for 60 GHz WPANs

André Bourdoux, Wireless Research Group, IMEC, Belgium

Abstract of the talk

Thanks to the availability of unprecedented bandwidth, the throughput offered by wireless systems in the 60 GHz band can potentially exceed the mythical barrier of 1 Gbps wireless, enabling the deployment of new applications such as wireless HDMI, wireless desktop or ad hoc conference networks. However, several challenges must be solved for these applications to become a reality. First, the link budget required to reach such bit rates is very challenging; second, front-end non-idealities at frequencies an order of magnitude higher than those of conventional wireless systems are reported by analog designers to be worse; third, the 60 GHz wireless channel can in some scenarios be affected by non-line-of-sight propagation and/or shadowing, thus requiring some form of equalization; and fourth, the sheer bit rate calls for very fast ADC and digital signal processing, implying that the complexity and power consumption must be carefully monitored.

In this talk, we will first introduce WPANs in the 60 GHz band, describing the possible applications, the propagation channel and the standardization context. Next, we will introduce candidate PHY layer solutions that at the same time meet the throughput requirements and relax the analog front-end design, in view of highly integrated full CMOS implementations. Our solutions rely on modulation techniques with low peak-to-average power ratios, easy equalization, good spectral properties and modest front-end requirements in terms of phase noise and ADC resolution. Furthermore, based on the characteristics of the propagation channel, we will show that adaptive beamforming is desirable to boost the link budget, reduce interference and, in some cases, reduce multipath. The receiver signal processing associated with the modulation techniques will be described and link level simulation results will be provided, highlighting the "front-end friendliness" of the modulation technique.
