Signals transmitting method for use in orthogonal frequency division multiplexing communication system, involves selecting orthogonal frequency division multiplexing signals as signal group, and multiplying coding sample with group

摘要

The method involves selecting a set of orthogonal frequency division multiplexing (OFDM) signals as a signal group in a time interval. A coding sample is multiplied with the signal group, where the coding sample is a standardized complex random number with an amplitude 1. The OFDM signals are transmitted to a common wave broadcasting network. The OFDM signals are generated based on a channel coding of the OFDM signals to be transmitted. An independent claim is also included for a device for transmitting signals using orthogonal frequency division multiplexing.
