Optimal intra-symbol transmit windowing for multicarrier modulation
(2006) Second International Symposium on Communications, Control and Signal Processing- Abstract
- Windowing of the transmitted blocks in a multicarrier
system yields an improved spectral containment of the
resulting basis functions, which allows larger transmit power compared to no windowing while fulfilling the power spectral density (PSD) requirements. Most transmit window designs proposed so far aim at maximising the mainlobe energy and thus the spectral containment of the transmit basis functions.
In this paper, we compute the transmit window that is
optimal in the sense of maximising the information rate for a time-dispersive Gaussian channel known to the transmitter and compare it to the maximum mainlobe-energy window.
It is shown that the maximum-rate window outperforms the

In this paper, we compute the transmit window that is
optimal in the sense of maximising the information rate for a time-dispersive Gaussian channel known to the transmitter and compare it to the maximum mainlobe-energy window.
It is shown that the maximum-rate window outperforms the
maximum mainlobe-energy window in terms of information
rate, particularly for low SNRs and for short cyclic extensions.
The out-of-band PSD characteristics of the maximum mainlobeenergy window is superior for short cyclic extensions but gradually deteriorates with the length of the cyclic extension. (Less)
