TRANSMITTING DIGITAL SIGNAL

摘要

An arrangement for coding digital symbols and transmitting them through at least two antennas (314 to 318). A coder (308) reads at least two symbols belonging to the same transmission block and forms channel symbols of the symbols of the transmission block by means of a block code. The coder (308) multiplies at least one symbol belonging to the transmission block by a first nonzero weighting coefficient and at least one symbol belonging to the transmission block by a second nonzero weighting coefficient, and the division ratio of the first and second weighting coefficients differs from values +/-1 and +/-j. The thus formed channel symbols are transmitted to the radio path (320) through the antennas (314 to 318).
