In most modulation schemes for a telecommunication system, a fast and efficient sinusoidal signal generator is needed. Here we report on an FPGA implementation of a versatile CORDIC Based Direct Digital Synthesizer (DDS). Most commercial lightwave communication systems use standard modulation protocols, such as phase-shift keying (PSK) and frequency-shift keying (FSK), whose implementation is supported by specialized dedicated hardware. The rapid expansion of the internet requires significant improvements in energy and bandwidth efficiency. Therefore, a new class of communication systems, namely quantum-measurement enhanced optical communication systems are being actively pursued. In those systems, a classical receiver is replaced with a quantum receiver, while transmitters are similar. Recognizing that properties of quantum measurement are in general different from that of a classical measurement, more complex modulation schemes than PSK and FSK turn out to be more beneficial. Digital synthesis of these signals requires a versatile DDS whose development is reported here. By design, it can generate signals with a nearly arbitrary combination of phase and frequency.
