Abstract :
An architecture, design, and analysis of a prototype TIA/EIA-136 TDMA in-building software radio base station is presented. The classical radio and “software radio” related noise and dynamic range components that affect performance are identified and quantified. IF bandwidth and sampling rate requirements are explained. Static receiver sensitivity and two-tone intermodulation test requirements are analyzed. The noise figure, ENOB, and sampling rate also determine the receiver static sensitivity. The analog sections of the radio are designed such that the dynamic range of the A/D converter is optimally designed for acceptable quantization noise at low levels and sufficient headroom for strong levels. The phase noise of the local oscillators (LOs) from both the desired and interfering channels degrades the sensitivity of the receiver; these effects have also been characterized
