Abstract
A method of transmitting data over a wireless communications channel comprises transmitting a plurality of blocks (70), in which each block (70) comprises a plurality of symbols (71, 72, 73, 74, 75) representing the data. The symbols are transmitted using time packing, or Faster-than-Nyquist signalling, such that each symbol in a block overlaps in the time domain with at least one other symbol in the block. A null guard interval (77) is included in each block, having a length that means that inter-symbol interference is not a cause of inter-block interference.
