Claim Text:
1. A multiple-input multiple-output (MIMO) signal processor comprising: a baseband processor configured to multiplex an input signal into at least a first signal part, a second signal part, a third signal part and a fourth signal part; a radio frequency integrated circuit (RFIC) configured to transmit the first signal part at a first frequency, the second signal part at a second frequency, the third signal part at a third frequency and the fourth signal part at a fourth frequency, each of the first, second, third and fourth frequencies being different; a front end including a summation device configured to join the first, second, third and fourth signal parts into an output signal following transmission from the RFIC; and a laser configured to transmit the output signal over at least one of a wireline communication medium and an optical communication medium, the laser modulating each of the first, second, third and fourth signal parts included in the output signal according to the corresponding first, second, third and fourth frequencies so as to provided frequency diverse long-haul transport of the output signal.
