Spacetime code (STC)[1]
Description
Code designed for wireless transmission of information (via, e.g., radio waves) such that the sender can send multiple times from multiple locations. A spacetime code uses a modulation scheme to encode a message into signals that are sent at different times through different antennas, thereby utilizing both spatial and temporal (i.e., spacetime) degrees of freedom.
Rate
Shannon capacity of various multiple-input multiple-output (MIMO) channels has been determined [2–4].

- Spacetime block code (STBC) — Spacetime codes also use spatial and temporal diversity, but do not necessarily use blocks as codewords.
Cousins
- Hayden-Nezami-Salton-Sanders bosonic code — Hayden-Nezami-Salton-Sanders codes have been considered in the context of spacetime replication of quantum data [7,8], while STCs are designed to replicate classical data.
- Codeword stabilized (CWS) code — CWS codes have been considered in the context of spacetime replication of quantum data [7,8], while STCs are designed to replicate classical data.
