| Sumario: | This work presents the design and implementation of a phase-modulated signal generator, which allows a widerange of variation in its transmission parameters. The implemented circuit uses a minimum amount of FPGA resources. This was possible since the developed design stores a quarter cycle of the carrier, then the control logic decides which samples to take to obtain the established frequency and number of cycles per data, allowing a great variation. The output power of the signal is also configurable. In addition, the developed system allows data to be received through an external input or generated internally through a pseudo-random number generator (PRNG). The circuit was implemented using an FPGA (Field Programmable Gate Array) and a digital-analogue converter (DAC). |
