This
project analyses the performance of three transmitter based methods
namely Energy detection, Cyclostationary feature and Matched Filter
detection for a primary user on a GSM900 signal over a Rayleigh Fading
channel. In addition the project will also simulate and analyse the
performance of co-operative sensing technique using different numbers of
secondary users, and review how it seeks to solve the hidden node
problem.
Design Process
- A
primary signal with GSM900 centre frequency (for example 936MHz given
in section 1). The code should also include a plot of this signal in
time domain and its FFT.
- ROC curve for the Energy Detection Method over a Rayleigh channel for the signal mentioned above.
- A plot of the Probability of Detection vs SNR for Energy detection Method.
- ROC curve for the Cyclostationary Feature detection Method over a Rayleigh channel for the signal mentioned above.
- A plot of the Probability of Detection vs SNR for Cyclostationary feature detection Method.
- ROC curve for the Matched Filter detection Method over a Rayleigh channel for the signal mentioned above.
- A plot of the Probability of Detection vs SNR for Matched Filter detection Method.
- ROC curve for the Co-operative Spectrum sensing Method over a Rayleigh channel for the signal mentioned above.
- A plot of the Probability of Detection vs SNR for Co-operative spectrum sensing Method.
Evaluation
of performance is expected to be mainly based on ROC curves for the
subject spectrum sensing techniques.The propagation channel considered
is Rayleigh Fading channel.
