摘要： For reducing a peak value in single-carrier modulated or multi-carrier modulated digital transmitter signals, the peak value is first determined from a plurality of transmitter symbols contained in the digital signal. If a predetermined value is exceeded, a replacement symbol is generated which replaces a predetermined transmitter symbol. The replacement symbol is so chosen that it lowers the peak value and is convertible into the original transmitter symbol without error using a coding which was used to create the transmitter symbols.

摘要： A transmitting apparatus for transmitting signals in a multi carrier system on the basis of a frame structure, each frame including at least two signalling patterns adjacent to each other in the frequency direction and at least one data pattern. Frame forming means arranges signalling data and pilot signals in each of said at least two signalling patterns in a frame and arrange data on frequency carriers of said at least one data pattern in a frame. Scrambling means scrambles the signalling data by use of a unique scrambling sequence. Transforming means transforms said signalling patterns and said data patterns from the frequency domain into the time domain in order to generate a time domain transmission signal. Transmitting means transmits said time domain transmission signal.
