METHOD OF CODING A SIGNAL, TRANSMITTER AND RECEIVER

摘要

The invention relates to a method of encoding a digital signal, to a receiver and to a transmitter comprising means (308) for encoding symbols, comprised of bits, in blocks of a given length, means (308) for encoding each block into a given number of channel symbols to be transmitted over several separate channels, and at least three transmit antenna paths (314 to 318) for transmitting the channel symbols. In the solution of the invention, the transmitter comprises means (304, 208) for converting the symbols into a form in which the sum energy of channel symbols mapping at least one symbol in a block is higher than the sum energy of channel symbols mapping another symbol in the block.
