title = "On the use of TCH sequences for synchronization, channel and noise estimation",
abstract = "TCH sequences have been studied for codespreading and channel coding, but its true essence if that of synchronization and channel estimation. This is due to their property of being (almost) orthogonal to all sequences obtained via circular shifts. This property is extremely useful for time-offset synchronization (there is a distinct {"}peak{"} only when both sequences are aligned), and for dispersive channelestimation (since the multipath-taps are now orthogonal to each other). Alongside the use of the TCH sequences, a sequence of equal symbols is also employed for frequencysynchronization - essential for correcting the phase offset between estimates (especially for high offset values), and thus allowing for the posterior signal-processing.",
