Abstract

Stanford researchers in John Cioffi's lab have developed a method for allocating resources (bit rate and transmit power) in multi-user, multi-carrier communication systems. The invention provides the optimal power allocation algorithm for the equal-length DSL loops. Additionally, this invention provides a multi-user bit-loading algorithm for general multi-user multi-carrier systems.

Applications

Broadband transmission
Wireless multimedia
DSL

Advantages

Improved performance between systems
Improved downlink capacity
