An NLOS-capable 60 GHz MIMO demonstrator: System concept & performance

Paper i proceeding, 2011

In this paper we present a 60 GHz 2 × 2 MIMO demonstrator which has been developed to accomplish robust line-of-sight as well as non-line-of-sight indoor transmission. The physical layer concept is based on Code-Spread Orthogonal Frequency Division Multiplexing (CS-OFDM) and Alamouti Space-Time Coding (STC) to make maximum use of both frequency and space diversity. The highly modular, reconfigurable hardware implementation comprises commercial FPGA platforms and selfdeveloped extension modules up to fully integrated TX/RX 60 GHz frontends in III-V technology.We present results of transmission experiments conducted in a small office environment, which exemplary illustrate the capabilities and the performance of the presented approach. © 2011 IEEE.
