Abstract:
An apparatus for transmitting information, comprising:a bitstream source for providing a bitstream representing the information;a redundancy adding encoder for generating an encoded bitstream based on the bitstream provided by the bitstream source wherein the encoder is arranged to output, for a first number of input bits, a second number of output bits, the second number of output bits having at least twice as many output bits as the first number of input bits, and wherein the second number of output bits includes two portions of output bits, each portion of output bits individually allowing the retrieval of information represented by the first number of input bits, and the first portion of output bits being coded based on the bitstream in a different way with respect to the second portion of output bits;a partitioner for partitioning the second number of output bits into the two portions of output bits;a transmitter for transmitting the output bits of the first portion via a first channel and the output bits of the second portion via a second channel, the second channel being spatially different from the first channel;the transmitter being a single transmitter;the first channel being defined by the single transmitter and a first position of a mobile receiver;the second channel being defined by the single transmitter and a second position of the mobile receiver; andthe transmitter further includes delay means for delaying the second portion of output bits transmitted via the second channel such that time diversity is obtained.
