摘要：

This work presents a comparison of the results of measurements of average delay and RMS delay spread in an urban environment using different sequences of information for an OFDM channel sounding signal. The sequences evaluated arc a random sequence, a Pseudo-Noise sequence (PIN) and the Zadoff-Chu sequence (ZC). The measurements were carried out in urban areas of Rio de Janeiro - Brazil, with a 20 MHz bandwidth signal with a central frequency of 773 MHz. The results are influenced by the autocorrelation properties of each sequence. In order to obtain compare the values of average delay and RMS delay spread obtained with each sequence, the measurements were performed under the same conditions.
