✦ Synopsis

A new algorithm for 16QAM carrier phase estimation using QPSK partitioning is presented in this paper. The estimator performance is close to the CramΓ©r-Rao lower bound (CRLB). In particular the performance of the new algorithm is compared to the CRLB for very short packets and shows that the equivalent loss in SNR is less than 0.5 dB for 20 symbol packets at 16 dB. The estimator is very suitable for fast acquisition performance in radio transmission systems, which may be required for burst transmission systems or conditions where the phase can change rapidly, e.g., multipath fading or local oscillator phase noise. The algorithm can be readily implemented in real time using digital signal processing techniques. ο›™ 2002 Elsevier Science (USA)

his paper presents a new motion estimation algorithm to improve the performance of the existing searching algorithms at a relatively low computational cost. We try to amend the incorrect and/or inaccurate estimate of motion with higher precision by using Kalman filter. We first obtain a measurement
