Some properties of Alamouti-like MISO codes

In this paper we are discussing multiple-input single-output (MISO) transmission in slowly fading channel with two transmit and one receiving antenna. Particularly we are concentrating on properties of division algebra based Alamouti-like space-time block codes. The main contributions of this paper are the following. First we extend the previously done constructions by considering general orders and give a simple proof that the proposed family of codes is approximately universal in the slow fading channel. Further we give a method to measure the pairwise error probability (PEP)-oriented normalized coding gain of the proposed codes and explore the frontiers of the achievable coding gain.
