A system and method for increasing bandwidth efficiency and data transmission
performance
of radio frequency wireless, optical wireless and fiber-optic digital communication
links without requiring an increase in signal power. The system utilizes bandwidth
efficient space-time coding to correct transmission errors and bandwidth efficient
space-time modulation to dramatically increase data throughput without requiring
additional signal bandwidth or power. Radio frequency wireless, optical wireless
WDM and fiber-optic applications are achieved by utilizing space-time encoders,
radio frequency sources, bandwidth efficient space-time modulators and power amplifiers
combined with transmission devices such as one or more antennas, multifeed antennas,
multimode antennas or for transmission by a suitable cable. At the receiver, the
method is reversed.
