Abstract

TCH sequences have been studied for codespreadingand channel coding, but its true essence if that ofsynchronization and channel estimation. This is due to theirproperty of being (almost) orthogonal to all sequencesobtained via circular shifts. This property is extremely usefulfor time-offset synchronization (there is a distinct "peak" onlywhen both sequences are aligned), and for dispersive channelestimation(since the multipath-taps are now orthogonal toeach other). Alongside the use of the TCH sequences, asequence of equal symbols is also employed for frequencysynchronization- essential for correcting the phase offsetbetween estimates (especially for high offset values), and thusallowing for the posterior signal-processing.
