Abstract:

We propose to estimate time-varying frequency-selective channels using data-dependent super- imposed training DDST and a basis expansion model BEM. The superimposed training consists of the sum of a known sequence and a data-dependent sequence, which is unknown to the receiver. The data-dependent sequence cancels the effects of the unknown data on channel estimation. Symbol detection is performed using MMSE equalization. The method is compared to time-division-multiplexing-based methods.
