Adaptive equalization for burst signals in dispersive channels
MetadataShow full item record
In this thesis a method is developed to estimate and remove group delay caused by the transmission channel in the case of a burst signal. The signal of interest is modeled as burst white noise, and no information about any underlying symbol structure or rate is assumed. The regions of transition between the signal present and the signal not present are used to estimate the group delay of the transmission channel. Once estimated, the group delay can be removed using an all-pass lter with the proper phase characteristics.
