Wideband Channel Measurement at 2.6 GHz Using Slippage Correlation and Amplitude Distortion Correction Algorithm

The measurement and analysis of wideband mobile channel are the foundations of network coverage and wireless network optimization. An outdoor propagation measurement campaign in which the sounding signal is PN sequence at 2.6GHz has been performed in Beijing recently, and the result shows that slippage correlation based on PN sequence is capable to probe the channel impulse response (CIR). However, considering the inter-path interference that affects the result, an amplitude distortion correction algorithm is proposed to eliminate inter-path interference and enhance the accuracy of channel parameters. Moreover, results including the effect of the correction algorithm are analyzed and compared with that of traditional algorithm.
