  • Software defined radio (SDR) filter relaxation technique for multiple-input and multiple-output (MIMO) and large antenna array (LAA) applications
    Patent number: 11251822
    Abstract: An example method of operating a radio system includes receiving, over a receiver-path, an RF input signal from an antenna, and converting the RF input signal to fall within a pre-defined frequency range using a local oscillation signal. The method further includes processing the converted input signal with a standard filter. In some examples, the method further includes generating the local oscillation signal in a transmitter path of the radio system.
