Phase Coding

A new method is proposed to design composite waveform for MIMO radar based on phase coding and linear FM. Compared with the traditional MIMO phase coding signal, the new method has some merits such as the wide bandwidth and being realized in practice. The optimizational cost function is formulated, and simulation experiments verify the correctness of theory analysis and validity of optimizational method.

This paper deals with the problem of carrier frequency estimation for MPSK symbols. We present a novel non-data-aided method by introducing a step factor into an earlier estimation algorithm to reduce the computational complexity with little loss of the estimation accuracy. We also make some comparisons with earlier algorithms. From the results of simulations, we make the conclusion that the new method can separate the estimation range and the estimation accuracy, and avoid the weakness of reaching large estimation range at the expense of estimation accuracy.

Location Based Service

Location based service (LBS) is more and more important nowadays. Assisted with GNSS, Base Station Positioning System (BSPS) can offer seamless outdoor & indoor positioning. The fading channel causes problems in signal acquisition. In this paper, a new method of RAM-based frequency acquisition is introduced, which can acquire the residual carrier frequency in fading channel accurately.
