With the demand for wireless personal communications growing exponentially, complex modulation schemes have been deployed that offer the spectral efficiency to support the
demand with fixed spectrum. Modulation formats of this type typically present difficulties for power amplification due to the statistics of the envelope of the signal, often referred to as peak-to-average power ratio or crest factor. Most client base stations employ Class A and Class AB amplifiers. The WiMAX era is erupting as several companies have already announced successful trails for 802.16-2004 (TDD) compliance.Most of the WiMAX base stations that are deployed have gaps in the coverage. In order

Most of the WiMAX base stations that are deployed have gaps in the coverage. In order to ensure quality of service (QOS), higher-power base stations are being developed to close the gaps and extend coverage.
