Abstract
A method and system for increasing the throughput of a wireless channel that sends different data on different multi-path components. The channel can be pre-mapped or dynamically mapped, and the different transmissions can be modulated by different complexity signals such as adaptive quadrature amplitude modulation (AQAM). Each multipath component is coded with a signature that will allow it to be separated at a receiver that has an omni-directional antenna. Common signature techniques can be offset PN codes, orthogonal spreading vectors, orthogonal alphabets and other signature techniques. The received channels can be combined for an overall increase in data-rate or used separate as multiplexed data.
