A base station (140) and a method (400) are described for providing transmit diversity. The base station generates a first signal based on a first data stream with a first pilot and a second data stream with a second pilot. The first signal includes the first and second pilots, which first pilot and second pilot are respectively based on a first orthogonal code and a second orthogonal code. The base station generates a second signal based on the first data stream with the first pilot and the second data stream with the second pilot such that the second signal including the first and second pilots is diverse relative to the first signal. Further, the base station phase-shift modulates the first signal to produce a phase-shift modulated signal. The base station transmits the phase-shift modulated signal via a first antenna (210) and the second signal via a second antenna (230).
L'invention concerne une station (140) de base et un procédé (400) permettant de produire une émission en diversité. La station de base génère un premier signal comprenant un premier train de données associé à un premier pilote, et un second train de données associé à un second pilote. Le premier signal contient le premier et le second pilote, lesquels comprennent respectivement un premier code orthogonal et un second code orthogonal. La station de base génère un second signal formé du premier train de données associé au premier pilote et du second train de données associé au second pilote, ce second signal contenant le premier et le second pilote étant généré de manière à présenter une diversité par rapport au premier signal. La station de base module en outre le premier signal par déphasage de manière à produire un signal modulé par déphasage. La station de base émet le signal modulé par déphasage par l'intermédiaire d'une première antenne (210) et le second signal par l'intermédiaire d'une seconde antenne (230).
