| Résumé : | The evolution of radio communication systemstowards millimeter-wave (mm-wave) frequencies allows fornew opportunities in terms of localization and environmentmapping. The increase in bandwidth and size of antennaarrays creates great similarities between 28 GHz communication systems and radar systems. There are severalchallenges to use 28 GHz communication systems forenvironment mapping: 1) it is unclear whether multipathcomponents can be identified with arrays that rely onbeamsteering, 2) the local oscillator (LO) is not sharedbetween the transmitter and the receiver, causing considerable LO frequency offsets, and 3) the high power of theline-of-sight component tends to “blind” the receiver toall other multipath. In this paper, we realize (relatively)low-cost 28 GHz software-defined radio-based transceiversthat use 4×4 antenna arrays. The transceiver architectureis presented, and the setup is used to perform somepreliminary measurements. These first results indicate thatsome amount of multipath components can be recovered,even with limited angular resolution of a 4×4 beamsteeringarray. |
