Analog and Digital Communication Mini Projects | FM, Telecommunication, Mod...

 

Mini Project Ideas


1. You can do your mini project on analog communication topic such as FM, walkie-talkie, etc.

[1.1] Analog Communication Based Project

[1.2] MATLAB Code for Frequency Modulation (FM)


2. Compare the ASK, FSK, and PSK systems' relative performances.

(Include an introduction, concise descriptions of ASK, FSK, and PSK, MATLAB, and Simulink. You can then compare ASK, FSK, and PSK by creating BER vs. SNR graphs for each of those modulations, as well as by comparing their bandwidth, noise resistivity, complexity, and other characteristics.)

3. M-ary Modulation Based Mini Projects

(You can go for this project if you are interested in doing projects based on frequently used and modern modulation techniques. You can compare the performance analysis of various modulation schemes, like, bit rate, complexity, SNR v/s BER graph. You know frequently used modulation technique is m ary QPSK. But now QAM is also becoming popular due to its less complexity. But there is still some limitations in QAM due to its capacity in the context of noise handling. On the other hand m ary QPSK is better for very large constellation points but this technique is more complex than QAM. So, your primary goal may be investigating up to how many constellation points QAM is better than QPSK. Although, now we don't need to transfer data using QPSK with large constellation points. Obviously, in real world QAM is still used. 

For this mini project you can include a comparison of  bit and baud rate of different modulation techniques. You can start from primary modulation techniques like, ask, fsk to QPSK or QAM)


3. Telecommunication based mini project

(Here, you can discuss mechanism of telecommunication - from end user to telephone exchange office and exchange office to gateway. You can also discuss uplink and downlink connection, operating frequency, modulation used for a particular generation wireless communication. You can include the role of fiber optics in case of telecommunication, etc.)


4. Role of Equalizer in Wireless Communication

MATLAB Codes for Various types of beamforming | Beam Steering, Digital...

Beamforming Techniques MATLAB Codes for Beamforming... The mathematical [↗] and theoretical aspects of beamforming [↗] have already been covered. We'll talk about coding in MATLAB in this tutorial so that you may generate results for different beamforming approaches. Let's go right to the content of the article. In analog beamforming, certain codebooks are employed on the TX and RX sides to select the best beam pairs. Because of their beamforming gains, communication created through the strongest beams from both the TX and RX side enhances spectrum efficiency. Additionally, beamforming gain directly impacts SNR improvement. Wireless communication system capacity = bandwidth*log2(1+SNR) bits/s. Thus, the capacity or overall throughput of the system increases.
