For conventional cyclic-prefix (CP)-assisted block transmission systems, the CP length is selected on the basis of the expected maximum delay spread. With regard to single-carrier (SC)-based block transmission implementations, a full-length CP is recommendable, since it allows good performances through the use of simple frequency-domain equalization (FDE)(More)

For conventional cyclic prefix (CP)-assisted single-carrier/frequency-domain equalization (SC/FDE) implementations, as well as for orthogonal frequency-division multiplexing (OFDM) implementations, the CP length is known to be selected on the basis of the expected maximum delay spread. Next, the data block size can be chosen to be large enough to minimize(More)
A new recursive echo cancellor (EC) for data transmission is proposed, where the output-error criterion and the equation-error criterion are used simultaneously. The combination of these two error criteria allows a fast initial convergence and leads to error surfaces with a single (global) minimum corresponding to unbiased parameter estimates, provided that(More)
