Abstract :
The feature of ADC/DAC and amplifier will affect the performance of DSP systems, especially those with non-constant envelop such as OFDM system. In this paper, we analyse their feature and simulative models, with which we investigate the performance of wireless local area network system based on IEEE 02.11a standard implemented with fix point DSPs. The amplifier and effective number of bits (ENOB) model are used to simulate the fix point performance of DSP. We provide test results with different devices parameters which are important for system designers.
