A kind of concise and higher bandwidth efficiency Variable Phase PPK (VP-PPK) modulation is proposed in this article. Base band pulse coding is analyzed, PSD expression for VP-PPK is deduced, and simulation is conducted. Coding realization of the system is given and performance simulation is given under the condition of AWGN channel. It is shown that bandwidth efficiency of VP-PPK can be log2N times that of RPPK, N is the integer power of 2, and the 3-dB bandwidth efficiency of VP-PPK can reach 39.32bps/Hz calculated according to the definition.
