== Comparasons with Space-Time Block Codes ==

In contrast to [[space-time block code|space–time block codes]] (STBCs), they are able to provide both coding gain and diversity gain and have a better [[bit error rate|bit-error rate]] performance.

* However, beingcurrent STBCs are based on [[trellis codes,]]. theyThis aremakes these codes 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.
