Patent ID: 8416879

Claim:
A multimode communication system, comprising: at least a first module comprising circuitry, the first module being operable to, at least: generate a first baseband wireless signal corresponding to a first wireless communication protocol; and generate a second baseband wireless signal corresponding to a second wireless communication protocol different from the first wireless communication protocol, the second baseband wireless signal characterized by a baseband frequency bandwidth of the second baseband wireless signal; and at least a second module comprising circuitry, the second module being operable to, at least: receive the first baseband wireless signal; receive the second baseband wireless signal; spectrally shift an in-phase (I) component of the received first baseband wireless signal to a frequency space beyond the baseband frequency bandwidth, the spectral shift including mixing the I component and quadrature phase (Q) component of the first baseband wireless signal with respective I and Q components of a mixing signal; spectrally shift the Q component of the received first baseband wireless signal to the same frequency space beyond the baseband frequency bandwidth, the spectral shift including mixing the I and Q components of the first baseband wireless signal with respective Q and I components of the mixing signal; and generate a composite wireless signal comprising, at an instant in time, an I composite component and a Q composite component, each composite component including a first component based on the spectrally-shifted first baseband wireless signal, and a second component based on the second baseband wireless signal that has not been spectrally-shifted.
