In this letter, a generalized extension of the linear Z4, space time (ST) code of  is conducted to obtain a linear Zω structure that can be flexibly used for various numbers of transmitter antennas, number of states, and modulation types. Additionally, the corresponding recursive systematic (RS) code structure is presented. The optimal code of the quadrature phase shift keying (QPSK) and 8 phase shift keying (PSK) modulation with 2 transmit antenna case is obtained from a code search and analyzed in comparison to the codes of . Additionally, the structure for the 8, 32, and other number of states that were not provided in  are presented in this paper.
