Projects & Seminars

I'm doing my Master's in Communications Engineering (majors in DSP) at Aalto University (TKK), Finland, under the supervision of Prof. Risto Wichman.

My Bachelor's thesis was based on the C6000 digital signal processors of Texas Instruments. I used it for the computation of Periodogram Smoothing of noisy signals. You can find the project report here:
Project Report: C6000_Smoothing

The problem considered was this: During the communication between two mobile phones, there is always an element of noise interference. Basically, we can split the noise into its component frequencies. Periodogram is one such technique based on the Fourier Transform. Once the noise frequencies are estimated, their amplitudes are reduced in a process called "Smoothing".

The implementation taken to solve the problem is split into three steps. First, the FFT (Fast Fourier Transform) is implemented in the assembly language of C6000. The actual algorithm of Periodogram Smoothing is written in C. This C routine calls the FFT assembly program as and when needed. Finally, a graphical user interface is provided to the C programs using MATLAB. In fact, all the plots and diagrams are done by MATLAB while the core of mathematical computations is all done in C. All the three (assembly, C, MATLAB) are integratred together to form a well-knit unit which can be loaded on the DSP processor.

In addition to this, the analog signal input is taken externally from a signal generator to which Gaussian noise is added. The A-to-D conversion is done by the processor. A simple program to configure the McBSP can be written using DSP/BIOS real-time operating system of TI.

I gave a presentation during the technical seminar a part of my graduation. The presentation was all about the TMS320C6000 processor. I discuss the processor architecure, concepts of pipelining and some general trends.

I must really admit that the technical documentaion by Texas Instruments was very good in preparation of the report.

I've also put the concepts in a slideshow. Click to download.
