In this paper it generate a self analysis and verification tool for the field trial data based on the simulation software in the setting of the system parameters for WiMAX base station. Through repeat reviewing and verification of the system specifications for the WiMAX system and the analysis of a series of field trial data to complete an analysis tool that has the attribute that it has been verified...
Some interference management measures in the PHY control to reduce possible interferences in the transmission between an MS and BSs are proposed. The design and assignment procedures to generate pilots to have lower interference levels are introduced and discussed. Based on the design process each pilot is accordingly assigned an interference weight with respect to a basic pilot and with this design...
A direct conversion transmitter for mobile WiMAX/WiBro applications is developed. It is composed of a reconstruction filter, an I/Q modulator, a four-stage RF programmable gain amplifier (PGA), and a power amplifier (PA) driver. A 7-bit digital-to-analog converter (DAC) is also implemented to compensate the DC offset in the modulator due to device mismatch. A 72-dB gain control range in 1-dB step...
