Methods for generating and transmitting frequency hopped signals

The invention claims a fixed and transmission frequency division multiplex signal method and device. The method suitable; and device in any assigns in time is a sleeve is a subset THE situations is AN subcarrier frequency. Each is FDM signal by combining multiple independent simulated sub-intelligence signal generation, the remote signal sub-intelligence the frequency is connected to form, for example, and time's frequency hopping function. Each a sub-intelligence analogue signal is enlarged, for example power amplification, and other end with the sub-intelligence signal of a filter. The filter is used to compensate or correcting the signal and/or for reducing between the rotor carriers interference. The fixing frequency filter is used for displaying the frequency hopping OFDM system. In one embodiment, a filter is programmable; and frequency hopping; the central frequency conversion in turn to match the subcarrier frequency for selecting. The programmable filter bandwidth and maintain constant.
