Diversity method and device

In a transmission/receiving, concept using a code speed is less than or equal to 0.5 and a addition, encoder to obtain the two data streams of two different launchers, wherein two launchers is configured between different space position. The receiver, received signal sampling is composed (40a) performing etching of the first thief of the first synchronous machine of said and output of wherein a second thief of the second synchronous machine (40b,) to obtain the first and second received signal, such received signal via is a check decoder (54) to obtain the first decoding (56a) and second (56b) for receiving the code device for secondary group, which is coated with a counting assembly (58) is equal the unwanted a signal, and other unwanted signals are (60a and 60b) to achieve an interference to reduce on the corresponding received signal facies set(60). The receiver concept of fast converging, and a secondary launchers to the bandwidth in the same frequency the transmission needed are launchers in different frequency emitting corresponding emitter concept of the width range.
