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

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 Codi...

Description
Summary: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 self-developed 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.
