Abstract
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.
