| Abstract: |
| The performance loss of interference between TD-LTE and TD-SCDMA syste
ms at 2.35 GHz frequency is analysed. The coexistence interference is simulat
ed only in a macro-to-macro cell scenario considering based on Monte Carlo. The
n the simulation results of the three scenarios are presented. To ensure the qu
ality of the network, maximize the system capacity, and make the simulation resu
lts scientific and credible, ACIR and interference models are improved to accomm
odate to the coexistence research of TD-LTE and TD-SCDMA systems. Then performan
ce loss is discussed in detail with different carrier frequencies, geographic lo
cation offsets, bandwidths, and power control parameters. What′s more, ACIR val
ues are provided about system coexistence. It provides valuable reference for th
e research of hybrid network planning and optimizing. |
