| 摘 要： | 针对230 MHz频段电力无线专网连续分配载波的情况，给出了提高频谱效率的优化设计。通过取消载波间的预留保护带，采用连续子载波频域资源映射、自适应FFT与滤波处理，减少了运算量，提高了业务速率。针对230 MHz电力无线专网两种技术制式标准统一的问题，给出了必要性和重用公网成熟终端与系统设备产业链的初步分析。

| Abstract: | An optimized design for improving spectral efficiency was given for the case where the power wireless private network in the 230 MHz band continuously allocates carriers.By canceling the reserved guard band between carriers,continuous subcarrier frequency domain resource mapping,adaptive FFT and filtering processing were used,which reduced the amount of computation and improves the service rate.Aiming at the problem of unification of two technical standards of 230 MHz power wireless private network,the necessity and the preliminary analysis of the mature terminal and system equipment industry chain of public network were given. |
