Abstract :
Punctured space-time trellis codes (STTCs) that preserve the diversity gain for short error sequences are derived. The rate 4/3 and 8/7 punctured STTCs achieve a two-level diversity gain for a frame size of 16, which require 1.3 and 0.7 dB more power to attain the same frame error rate compared with the STTC without puncturing.
