| Summary: | Utilizing antenna diversity techniques has become a well-known approach to improve
the performance of wireless communication systems. Multiple antenna arrays with half-length
spacing, such as a uniform linear array (ULA), have been taken into consideration. Since 60 GHz is an
unlicensed frequency band and ideal for local propagation, it is where the technology is being used.
The transmitter and receiver both accomplish QAM modulation and demodulation. The performance
in terms of bit error rate (BER) was tested in MATLAB simulation software for all antenna diversity
scenarios: the single input and single output (SISO) DWT, multiple input and single output (MISO)
DWT, single input and multiple output (SIMO) DWT, and multiple input and multiple output (MIMO)
DWT. The MIMO DWT was shown to be the best of them. The performance of MIMO OFDM using
various wavelets was also simulated, and the performance of the Haar wavelet transform was 2 dB
better than that of the other wavelet transform. Compared to simulation results, the analytical results
showed good agreement with little discrepancy |
