Analysis of channel capacity for UWB antenna for improvements in the data rates and low Power transmission over wireless application

Multiple input- Multiple output- Ultra-wideband (MIMO-UWB) is a wireless communication approach that combines multiple antennas at the transmitter and receiver with ultra-wideband frequency spectra to increase data speeds, dependability and spatial diversity in communication systems. The purpose of this research is to study the hybridization of MIMO-UWB over the Rayleigh fading channel using various antenna designs. Convolution encoders are used to encode binary data. The bit interleaver records the encrypted data that is sent to the mapper. The Inverse Fast Fourier Transform is used to handle information from Parallel subcarriers \(two, four,\) $two,four,$ and \(eight\) $\mathit{eight}$ . To prevent Inter symbol interference, a cyclic prefix is subsequently added. A Fast Fourier transform is used to synchronize signals after they are distorted and two, four, and eight antennas. The cyclic prefix is then deleted. Once the interleaving is done, the data received through various antennas are transformed into serial, demodulated, and decoded. Bit Error Rate (BER) and data rates are used to assess the hybridization system for MIMO-UWB sectorial antenna designs of \(2x2, 4x4\) $2x2,4x4$ , and \(8x8\) $8x8$ .The results obtained indicate that both traditional MIMO and combined MIMO-UWB have higher data rates as SNR increases, with hybridized MIMO-UWB having higher data rates than conventional MIMO and achieving low transmission power. In the same way, hybridized MIMO-UWB yields lower BER values than standard MIMO. This suggests that hybrid MIMO-UWB outperforms traditional MIMO in terms of Rayleigh fading.
