Bit Loading and Power Allocation in OFDM Communication System

摘要：

In this paper the OFDM transmission scheme has been briefly reviewed. As future communication systems are generally expected to convey higher and higher data rates and thus require larger bandwidths, OFDM systems can utilize larger system bandwidths by increasing the number of sub-carriers, which increases the symbol duration, while still maintaining a high overall symbol rate. The problem of resource allocation in a multiuser OFDM system is formulated. For a single user system, an improved water-filling algorithm is developed.
