Abstract:
A method for transmitting a multiplexed signal over an atmospheric channel, the multiplexed signal comprising at least two signals, one signal being an analog signal and at least another signal being a digital signal, the method comprising the steps of:amplifying said analog signal by employing a non-linear amplifier; amplifying said digital signal by employing a linear amplifier; transmitting said non-linear amplified analog signal in said atmospheric channel by employing a first antenna; and transmitting said linear amplified digital signal in said atmospheric channel by employing a second antenna, wherein said non-linear amplified analog signal and said linear amplified digital signal are non-interfering in frequency such that combined transmission of the non-linear amplified analog modulated signal and the linear amplified digital modulated signal forms a multiplexed signal in the atmospheric channel.
