This paper explores the use of kurtosis in synchronizing with a QPSK burst transmission. The start and end of the burst are a priori unknown and are detected without the use of pilot signals. After frame level synchronization, signal level synchronization is performed. The symbol timing, carrier frequency and carrier phase are recovered without the assistance of known symbols or synchronization words...
This paper analyzes an algorithm for synchronizing with a QPSK burst transmission. The symbol timing, carrier frequency offset, and carrier phase offset are estimated using a novel low-complexity kurtosis-based algorithm. The paper computes Cramer-Rao bounds for joint estimation of the synchronization parameters and compares the performance of the proposed estimation algorithm with these bounds.
