The need for mobile communication systems with high data rates and improved link quality for a variety of application has dramatically increased in recent years. Multiple antenna systems are an efficient means for increasing the performance. To utilize the huge potential of multiple antennas it is necessary to choose transmit strategies, referred to as space-time block code (STBC). For real orthogonal STBC design the code rate 1 can be achieved, for any number of transmit antenna. For complex orthogonal STBCs of two, three, and four transmit antennas have achieved rate of 1, 3/4 and 3/4 respectively. Complex orthogonal designs STBCs for other numbers of transmits antennas exhibit rates of 7/11 and 3/5 for five and six antennas respectively. In this paper we achieved full rate, generalized complex orthogonal space time block code for 4 transmit antenna.
