This paper introduces new variations about the codes recently introduced by Jafarkhani & al named Super Orthogonal Space Time Trellis Codes (SOSTTC). Using powerful set partitioning rules, these codes are able to combine the coding advantage of STTC's together with the advantage diversity of STBC. This partitioning is based mainly on the determinant criterion introduced first by Tarokh. Jafarkhani proposed, in the case of two transmit antennas, a general framework for the construction of SOSTTC with maximum coding rate equal to 1. The obtained results are quite outstanding with simple trellises. In this paper we propose a new application field of these codes in the context of turbo encoding schemes with parallel concatenation. We obtain excellent performances since the turbo codes enable to work within 1.2-1.3 dB from the theoretical outage capacity.
