Abstract
The transmitter output of the OFDM sys-
tem is known to have large spectral side-
lobes. Windowing and pulse shaping have
been proposed to reduce sidelobes in the lit-
erature. When these methods are used, addi-
tional post-processing equalization is needed
at the receiver. The post processing computa-
tions are often channel dependent and the co-
ecients need to be computed when the chan-
nel changes. In this report we consider win-
dow designs for the OFDM system. We will
design windows that minimize out-of-band en-
ergy with the condition that post processing is
channel independent.
