On the Pilot Arrangement for Channel Estimation in Modified MT-CDMA System

The fourth generation cellular mobile communication system in the future needs to provide high data rate transmissions. Multi-Tone CDMA (MT-CDMA) system combines the advantages of CDMA and OFDM, and it is one of the promising choices for the fourth cellular mobile communication system. In order to raise the performance, we amend MT-CDMA named Modified MT-CDMA. We use different pilot arrangement in different channel to enhance the channel estimation of system.
The receiver architecture includes a baseband signal detection and a channel estimation. We use a pilot symbol to estimation the channel. In this thesis, we make a study of pilot arrangement on different channel estimation performance of system. We use Least Square estimation(LS)¡Blinear interpolation¡Bspline interpolation¡BFFT/IFFT interpolation and spline interpolation combine FFT/IFFT algorithm to estimate the system performance.
