Abstract
In this paper, a flexible Remote Unit (RU) with
real-time modulation of 5G-like Orthogonal Frequency Division
Multiplexing (OFDM) signals, capable of transmitting in the
sub-6 GHz band, is presented. This architecture is capable
of multi-carrier transmission, with the present implementation
being able to transmit up to 3 distinct carriers and the overall
architecture being only limited by the number of transmission
chains implemented. The results show a maximum Error Vector
Magnitude (EVM) of 4.7%, with Adjacent Channel Power Ratio
(ACPR) above 47 dBc.
