Abstract
The MIMO technology towards achieving future
generation broadband networks design criteria is presented.
Typical next generation scenarios are investigated. The MIMO
technology is integrated with the OFDM technology for effective
space, time and frequency diversity exploitations for high speed
outdoor environment. Two different OFDM design kernels (fast
Fourier transform (FFT) and wavelet packet transform (WPT))
are used at the baseband for OFDM system travelling at
terrestrial high speed for 800MHz and 2.6GHz operating
frequencies. Results show that the wavelet kernel for designing
OFDM systems can withstand doubly selective channel fading for
mobiles speeds up to 280Km/hr at the expense of the traditional
OFDM design kernel, the fast Fourier transform.
