In Bioelectrical impedance measurement, the impedance accuracy is a very important parameter. With the analysis of general Digital Phase Sensitive Detection (DPSD) algorithm and its error, this paper presents an improved DPSD algorithm. In this method, it firstly decomposes the orthogonal signals which have passed through the networks, and then sums (minus) the relevant signals to get the parameters amplitude and phase. By this way, it can avoid errors caused by filtering operation in general DPSD algorithm. At last, the paper gives a simulation which can be hardware-based achieved. The result proves the effectiveness and feasibility of this improved method.
