Multiple Co-Polar Co-Channel Point-to-Point Radio Transmission
Abstract:The use of multiple antennas both at transmitter and receiver improves the spectral efficiency in wireless communications. We propose a multiple antenna system, which is tailored for the scenario of line-of-sight fixed radio. The interference is removed by means of an equalizer operating at the receiver side without any onerous pre-processing at the transmit side. A suitable choice of the spatial separation among the individual transmit/receive antennas guarantees not only the possibility to re-use the frequency band but also an increase in the power efficiency respect to a single-input-single-output system.
