| Abstract: | The paper researches the Nyquist Pulse and the rise cosine pulse based on the optimum wave theory and the Nyquist principle,by using base-band pulse figuration and rolling efficient circulation filtrated technologies.A new type IJF code with fine performance,low envelope fluctuation was designed. Simulation results show that compare to the rise cosine pulse,with the narrow main valve and the faster high frequency rolling and the better resisting of spectral spreading,the new type IJF code has better performance. |
