Abstract:
1. A transmitter for transmitting on a first transmit path and on a second transmit path, comprising: an encoder configured to encode two input symbols into four output symbols and compute a spread delay, wherein a first symbol and a fourth symbol of said four output symbols carry first information and a second symbol and a third symbol of said four output symbols carry second information, said first symbol is transmitted on said first transmit path during a first transmission period, said second symbol is transmitted on said first transmit path during a second transmission period, said third symbol is transmitted on said second transmit path during said first transmission period, said fourth symbol is transmitted on said second transmit path during said second transmission period, said first and second transmit paths correspond to input paths of a communication channel; and a selector configured to only delay symbols transmitted in the second transmission period by the computed spread delay, wherein the computed spread delay is a number of transmission periods between said first transmission period and said second transmission period, and is larger than a maximum length of channel disturbances of the communication channel.
