Method for generating transmission signals or OFDM symbols in a communication system and communication system device
摘要
Data from one or more users (I) or from one or more data sources is mapped onto multiple sub-carriers (Nc) for a carrier. Data is inserted in blocks in order to form an orthogonal frequency division multiplexing symbol (OFDM) in a time sequence after a safety interval. Data from the data source is encoded by channel, modulated before mapping onto multiple sub-carriers and transformed as an expansion via fast Fourier transformation (FFT). An independent claim is also included for a communications systems device for carrying out the method of the present invention.
