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 in terms of subcarrier, bit and corresponding power of QoS for real time services in multiuser OFDM systems (13 in Fig. 1). The invention takes advantage of the instantaneous channel gain in subcarrier and bit allocation using an iterative approach (Fig. 3).
