Patent ID: 8831073

Claim:
A wireless transmission system comprising: a transmission-side frequency converter configured to convert a subject signal into a modulated signal, said transmission-subject signal modulated with a modulation carrier signal becoming said modulated signal; a transmission-side antenna configured to radiate an amplified signal, said modulated signal after amplification becoming said amplified signal; a reception-side antenna configured to receive said amplified signal from the transmission-side antenna, said amplified signal after reception by the reception-side antenna becoming a received modulated signal; a reception-side demodulation functional unit configured to output a synchronous detection signal, said received modulated signal mixed with an oscillator signal becoming said synchronous detection signal; a reception-side injection locking controller configured to generate an injection signal from said synchronous detection signal, said injection signal controlling said reception-side demodulation functional unit to synchronize said oscillator signal with said modulation carrier signal, wherein said transmission-side frequency converter and said transmission-side antenna are within a housing of a first electronic apparatus.
