Process-Stacking Multiplexing Access for 60 GHz Millimeter-Wave WPANs

摘要

Millimeter-waves technology shows high potential for future wireless personal area networks, reaching over 1 Gb/s transmissions using simple modulation techniques. This technology is on the innovation stages; therefore current specifications consider dividing the spectrum into effortlessly separable spectrum ranges. In this work, a process-stacking multiplexing access algorithm is designed for single channel operation. The concept is intuitive and simple, but its implementation is not trivial. The key to stacking single channel events is to operate while simultaneously obtaining and handling a-posteriori time-frame information of scheduled events. This information is used to shift a global time pointer that the wireless access point manages and uses to synchronize all serviced nodes. The performance of the proposed multiplexing access technique is lower bounded by the performance of legacy TDMA and can improve the effective throughput significantly. Detailed implementation is presented and hypothesis is validated by simulation results.
