TD-SCDMA Slot Structure
A TD-SCDMA time slot has been designed to fit into exactly one burst. The time slot
(Figure 2-3) consists of four parts, a
midamble
with 144 chips duration, and two identical
data fields with 352 chips duration at each side of the midamble and followed by a 16
chips guard period. The midamble is used by the receiver to carry out channel estimation
tasks.
