  A new class of space time codes with high performance is presented. The code
design utilizes tailor-made permutation codes, which are known to have large
minimal distances as spherical codes. A geometric connection between spherical
and space time codes has been used to translate them into the final space time
codes. Simulations demonstrate that the performance increases with the block
lengths, a result that has been conjectured already in previous work. Further,
the connection to permutation codes allows for moderate complex en-/decoding
algorithms.
