We will develop Optimized Numerically controlled Oscillator for digital communication systems. In order to achieve this goal, several steps need to be followed. The first step is to find the different structure of NCO, and choose a traditional NCO structure. After defining the NCO structure, optimized NCO by algorithm and different technique. There are a large number of algorithms and methods in the signal processing literature. Therefore, the state of art algorithms and different methods should be analyzed and compared. Based on different algorithms and methods, different power consumptions, area and speed of the NCO will be achieved. So their ASIC suitability should be analyzed and the effort should be focused on the choosing algorithms and architectures and optimization. Furthermore, the improvement space should be analyzed and the architecture should be further optimized. The proposed algorithm and architecture should be validated by MATLAB simulation before implementation. After that, it is implemented on DSP Processor kit with Code Composer Studio. The synthesis results will be compared with other published FFT processor results. The proposed CORDIC based algorithm can significantly reduce the die size.
