The application of µ-Law companding to mobile WiMax

Research output: Chapter in Book/Report/Conference proceedingChapter


The IEEE802.16e mobile WiMax standard employs Orthogonal Frequency Division Multiplexing (OFDM) principles in the transmission of data (IEEE802.16e, 2005). Within multicarrier systems, like WiMax and other OFDM technologies, a major problem relates to issues associated with instantaneous values of the peak transmission output power. At some instant in time, the subcarriers of an OFDM signal may add coherently producing a very high peak power that may reach a maximum value of the number of subcarriers times the average power.
