<p>The present invention provides a new and unique method and apparatus to generate a sequence of symbols to be transmitted, comprising transmitting a block of symbols having data symbols and redundancy symbols, the redundancy symbols being generated based on the data symbols, a first part of the redundancy symbols being transmitted as a prefix of the block, a second part of the redundancy symbols being transmitted as a postfix of the block and a third part of the redundancy symbols being transmitted as an intermediate part of the block between the prefix part and postfix part. The first part of the redundancy symbols may be generated from the symbols that are transmitted at the end of a data portion of the block, the second part of the redundancy symbols may be generated from the symbols that are transmitted at the start of the data portion of the block, the third part of the redundancy symbols (which are transmitted in the second half of the data portion of the block) may be generated from an entire sequence of non- redundant data symbols that are transmitted in the first half of the data portion of the block and the block may form part of a continuous phase modulation (CPM) waveform that is substantially symmetric-periodic.</p> |
