与OFDM相比较,WMCM的基带调制时间复杂度降低,峰均功率比更优,对抗脉冲干扰的能力更强。
As it is to OFDM, WMCM has lower time complexity in baseband modulation, good PAPR distribution, and takes on more robust to pulse interference.
但是存在于两组功率级之间的些微差异会造成彼此的电流产生不平衡的状况,使得系统的可靠度降低。
However, the mismatch of two power stages in dual-phase architecture will produce current sharing between them, and system reliability decreases.
随后为降低求解该优化问题的复杂度,提出两步次优算法,将问题分解为子载波分配和功率分配。
Then, to reduce the complexity, we propose a two-step suboptimal algorithm that separates subcarrier and power allocation.
该方、去通过固定排序后的子信道的功率和比特分配方案大大降低了复杂度。
A low-complexity bit and power allocation algorithm is proposed based on this structure.
其主要特点是:节能——同等产量降低电功率40%,以平均每小时节约6度电计算,日生产可节约30元电费。
Its main features are: Energy — equal to lower production of electric power 40%, saving an average of 6 kilowatt-hour basis, savings of 30 per day production of electricity.
