CIR MEASUREMENT SYSTEM FOR CHARACTERISATION OF WIDEBAND COMMUNICATION CHANNELS IN THE 2.4 GHZ ISM BAND

Andrew H. Kemp – Edmund B. Bryant

   A 2.45 GHz pulse compression, channel impulse response (CIR) system is described. The motivation for its development and results verifying its performance are given. The system is shown to be an effective test and measurement tool for analysis of 2.4 GHz ISM band channels particularly for spread spectrum communication system deployment. The required signal processing is described and, because of the importance of spurious free dynamic range, the potential effects of even small inter-modulation products are considered.
