The classical 4-phase constant-amplitude zero-autocorrelation (CAZAC) sequence with the length of 16 has been used for multifarious purposes such as channel estimation and frequency/timing synchronizations since it presents good performance even in low signal to noise ratio (SNR) conditions. However, as multiple transmit antennas are employed, its properties are easily destroyed by the effect of multipath. In this letter, we propose a technique which ensures that the conventional CAZAC sequence is reliable in a multi-antenna system by inserting nulls. The performance of the modified sequence is verified through the mean s quare error (MSE) performance with the least squares (LS) method.
