Sommario
On October 9th, 2024 at 10.30 am the seminar titled "Millimeter Wave Communication Without Beam Alignment" will take place at DEIB Conference Room "Emilio Gatti" (Building 20).
Various applications are not suited for beam alignment: For the IoT, beam alignment may contain too much overhead. For real-time applications, its link set-up may be too slow.
In this presentation, an alternative to beam alignment based on a new continuous phase frequency shift keying is proposed. It combines the constant envelope of frequency modulation with low-rate repetition coding in order to compensate for the absence of transmit beamforming. Although it is a frequency modulation, its transmit signal shows close to rectangular spectral shape. Similar to GSM's Gaussian minimum shift keying, it can be well approximated by linear modulation, when combined with differential precoding. This allows for easy coherent demodulation by means of a windowed fast Fourier transform.
