Project Description:

CHAPTER 1: Performance evaluation of different modulation schemes in simple radio channel models

-Error performance evaluation via analytical analysis and Monte Carlo simulations in MATLAB of:
-Binary PPM (Pulse Position Modulation)
-Binary PAM (Pulse Amplitude Modulation)

CHAPTER 2: Performance evaluation of different receiver types and radio channel models for pulse communication
-Radio channel models in different environments
-Analysis of :
-Receive types : MMSE, ML, RAKE receivers
-Impact of the number of RAKE receiver’s branches

Analyze different channel models in different environments and how they are affected from the physical environment. Moreover, how optimal receivers work will be discussed and how these can be improved.

CHAPTER 3: Evaluation of the impact of synchronization errors and noise

Time synchronization and multipath diversity impact on the performance of an Ultra Wideband system will be analyzed.

CHAPTER 4: Extension of the analysis to MIMO systems

A. CHAPTER 1 - Performance evaluation of different modulation schemes in simple radio channel models

In this section, two (2) modulation schemes (PPM and PAM) will be analyzed. Their characteristics and how they work will be presented, an error performance calculation for each of them will be held and the time shift value will be found for optimally spaced signaling. Mathematical expressions will be used for finding the desired results and for comparing the error performance results of the different modulation schemes, MATLAB will be used to simulate and graphically represent them.

B. CHAPTER 2 – Performance evaluation of different receiver types and radio channel models for pulse communication

Different channel models (i.e. Turin’s model [1]) will be investigated and how the signal distorts and fades and how the effects of the multipath fading can be measured with a RAKE receiver. Moreover, how inter symbol interference is caused and how can be confronted will be marked and finally, how the optimal receivers work will be discussed.

C. CHAPTER 3 – Evaluation of the impact of synchronization errors and noise

This section will report the effects of time synchronization in the communication between the transmitter and the receiver in Ultra-wideband systems. It will be explained what happens if the terminals are not synchronized.
Multipath diversity effects will also be investigated and how correlation is done. Also, an estimation of the average BER vs. SNR for different modulation schemes with different number of RAKE receiver’s fingers will be reported.

D. CHAPTER 4 - Extension of the analysis to MIMO systems

After investigating all the above tasks, the results of them will be simulated in MATLAB for different MIMO systems (i.e. 2x2, 3x3, etc.) and report the differences that will be presented.
