This work presents experimental results for a four-stream spatial multiplexing setup in a line-of-sight (LoS) wireless backhaul scenario at 60 GHz. With optimal antenna arrangement, a highly orthogonal wireless channel with a measured condition number of 1.42 is observed, whereby the channel tap distribution shows a dominant LoS component. Two different equalizers, symbol-wise and block-wise adaptive, are presented and evaluated in terms of error vector magnitude (EVM) performance and bandwidth efficiency. For both approaches, an error-free transmission with a throughput of 14.08 Gbit/s is demonstrated, thus validating the practical suitability of LoS MIMO for wireless backhaul applications.    «
