提出并实验验证了一种新型的调制方案--叠加脉冲幅度调制（SPAM），它具有成本低、对发光二极管（LED）的非线性不敏感等优点。多个光脉冲从LED阵列的不同空间位置发射，在自由空间线性叠加，实现SPAM。实验结果表明，在采用LED阵列的情况下，采用蓝光滤光片和RC后均衡技术，可以实现120 Mbit/s的数据传输速率，误码率为1 × 10（-3）。
We propose and experimentally demonstrate a novel modulation scheme called superposed pulse amplitude modulation (SPAM) which is low-cost, insensitive to non-linearity of light emitting diode (LED). Multiple optical pulses transmit parallelly from different spatial position in the LED array and overlap linearly in free space to realize SPAM. With LED arrangement, the experimental results show that using the modulation we proposed the data rate of 120 Mbit/s with BER 1 × 10(-3) can be achieved with an optical blue filter and RC post-equalization.
