A numerically-controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal.

The is a fully functional GPS SDR. It can accept real data or simulate its own data. It performs correlation, signal parameters discrimination, and loop filtering both code and carrier with the option of carrier loop aiding of the code loop. There ar

A basic Direct Digital Synthesizer consists of a frequency reference (often a crystal or SAW oscillator), a numerically controlled oscillator (NCO) and a digital-to-analog converter (DAC) [3] as shown in Figure 1. The reference oscillator provid
