Post subject: Smart Antenna  Performance Analysis
Posted: Fri Nov 05, 2004 7:59 am



I am a student. I have to simulate an adaptive smart
antenna system, that is an adaptive antenna array,
whose outputs are adaptively combined through a
set of complex weights (signal amplitude and phase
adjustments) to form a single output with beam steering
interference mitigation capabilities. I have to
show how the performance of an adaptive system is
related to the DOA spread of multipath signals and
the impact of the number of multipath on the performance
of an adaptive antenna system. The simulated system
has to be an optimum combining array with 8 omnidirectional
elements. I have to assume that there are 5 gaussian
multipath signals. I have to show on the X axis
the SNR at each antenna element and on the Y axis
the bit error rate (BER) of coherent demodulation
of BPSK at the array output. The variables that
I have to inspected in the simulation are: number
of elements, number of multipath, DOA (direction
of arrival) spread, beamwidth of the directional
antenna element and the number of element that will
be chosen for beamforming process. I have to simulate
two kinds of communication system: TDMA and CDMA.
Bynary phase shift keying (BPSK) modulation is used
in all simulation.I suppose flat rayleigh fading.
There is an adaptive antenna array performance simulation
software that may help me?

send me the algorithm and matlab
code you are implementing to this id "prashanthvreddy@rediff.com"
