Line 3:
In contrast to [[space–time block code]]s (STBCs), they are able to provide both coding gain and diversity gain and have a better [[bit error rate|bit-error rate]] performance. However, being based on [[convolutional code|trellis codes]], they are more complex than STBCs to encode and decode; they rely on a [[Viterbi algorithm|Viterbi decoder]] at the receiver where STBCs need only [[linear]] processing.
STTCs were discovered by [[Vahid Tarokh]] et. al in [[1998]].<ref name="construction">{{cite journal|author=Vahid Tarokh, Nambi Seshadri, and A. R.
