Abstract
Methods are provided for converting from half-duplex communication to full-duplex communication in a legacy wireless cellular system having a base station. A method includes providing in the base station separate transmit and receive paths for transmit signals and receive signals, respectively. The method further includes converting an uplink frequency band and a downlink frequency band for the base station to a same frequency band. The method also includes applying analog signal cancellation techniques at the base station to isolate a full-duplex wireless reception signal from a full-duplex wireless transmission signal.
