1. A method of transmitting data from a transmitter to a remote receiver using transmit diversity wireless communication, said transmitter comprising at least three transmit antenna, elements, the method comprising the step of encoding said data in symbol blocks, which includesmodifying signals to be transmitted over at least one of said transmit antenna elements as a function of channel information at least approximately related to the channel transfer function of the transmitted signals (h1, h2, h 3, and h4), such that the received signal can be detected at the receiver by a detection scheme using an orthogonal detection code matrix, the signals to be transmitted over at least one of said transmit antenna elements are modified so as to satisfy at least approximately the equation
