Abstract :
A novel design for a merged modulator-demodulator Wave-Radio Interferometer (WRI) transceiver operating in quadrature-phase shift-keying (QPSK) modulation is presented. In order to phase modulate an ultra-wide band (UWB) signal, the WRI transceiver has been designed to have a linear phase response in the frequency range 3.1-4.1GHz. To maximize the versatility of the design, the core of the proposed merged WRI transceiver is the integration of a SP4T switch, which alternates between modulation and demodulation operations using a field-programmable gate array (FPGA) board. This architecture makes the WRI transceiver integrable with different digital-based systems that require extensive signal processing capabilities.
