For high bandwidth efficiency and better performance of the satellite communication, a novel modulation and demodulation scheme named Ternary Coded Pulse Shape Modulation (TC-PSM) is proposed. By analyzing the character of high band satellite channels and the features of existing modulation schemes, TC-PSM scheme is presented. The performance of the TC-PSM scheme is analyzed theoretically and the...
The TEM observation shows that TiN coating changed over from columnar structure to compact texture after Zr + implantation. X-Ray analysis indicates that combining of N with Zr, Ti atoms and Ti 2 N would be transformed into TiN and ternary Ti (Zr, N) phases during Zr-implantation with high doses, high ion flux and annealing. Therefore, the wear resistance had improved obviously, the...
