This paper describes the details of a new method for improved spectral efficiency in a multigigabit millimeter-wave communication system, and the outdoor and indoor test results of a 6-Gbit/s concept demonstrator in the 81-86-GHz frequency band. Achieved aggregate data with a 2.4-bit/s/Hz spectral efficiency was the fastest wireless transmission published(More)
The enabling technologies and challenges in development of multi-gigabit wireless communication systems in the E-band are discussed. Potentials of the further improvement of the fixed wireless links performance and feasibility of development of the future ad-hoc or mobile wireless networks in the E-band are evaluated.
We are developing a multi-gigabit wireless test bed for demonstrating new technologies that are suitable for commercial broadband applications of the future. We are targeting the emerging millimetre-wave bands above 57 GHz and the data rates up to 10 Gbps or more. The test bed is used to test different network applications and signal processing algorithms(More)
—This paper presents a joint channel and mutual coupling estimation technique for wideband antenna array to achieve high speed wireless communications in the millimetre-wave frequency bands. The estimated channel frequency responses and mutual coupling matrix can be used to digitally calibrate a wideband antenna array in the frequency-domain, followed by(More)
