SUBCARRIER AND BIT ALLOCATION FOR REAL TIME SERVICES IN MULTIUSER ORTHOGONAL FREQUENCY DIVISION MULTIPLEX (OFDM) SYSTEMS

摘要

The method of the present invention provides efficient resource allocation i n terms of subcarrier, bit and corresponding power of QoS for real time servic es in multiuser OFDM systems. The invention takes advantage of the instantaneou s channel gain in subcarrier and bit allocation using an iterative approach.
