| 摘要 |
An apparatus for receiving and/or transmitting signals using orthogonal frequency division multiplexing, said apparatus being adapted for outputting a first output signal, comprising:a time synchronisation circuit, being adapted for determination of control information from a first signal, said first signal comprising at least of a first part being a non-orthogonal frequency division multiplexing signal and a second part being an orthogonal frequency division multiplexing signal, said determination of control information exploiting said first part of said first signal;said time synchronisation circuit, further being adapted for converting said second part of said first signal into a second signal, being in time domain representation;a transformation circuit at least converting said second signal into a third signal, being in frequency domain representation;a first frequency domain circuit, at least converting said third signal into said first output signal; andsaid second signal and said second part of said first signal being orthogonal frequency division multiplexing signals.
