Abstract
A method for designing an optimum STC in an HARQ system is provided, in which kth codes are detected which maximize the minimum squared Euclidean distance of the signal matrix of a combination code created by combining first to (k−1)th codes with a kth code. A kth code whose signal matrix has a maximum minimum determinant is selected as the kth retransmission code.

A method for designing a space-time code (STC) for a kth retransmission in a hybrid automatic repeat request (HARQ) system, comprising the steps of:
- detecting kth codes that maximize a minimum squared Euclidean distance of a signal matrix of a combination code created by combining first to (k−1)th codes with a kth code;
- and
- selecting a kth code whose signal matrix has a maximum minimum determinant as the kth retransmission code.
