摘要

将M-ary脉宽调制(M-PWM)和双边脉宽调制(DPWM)与带宽受限信道中的非归零(NRZ)调制进行了比较。在给定的数据速率下，与NRZ相比，DPWM具有将能量集中在较低频率的频谱特性。本文研究了有利于DPWM传输的信道特性。在两个不同的电通道上以10gb /s的速度比较每种调制格式，以研究相对于固定数据速率和固定最小脉冲宽度的信号完整性。

Interconnect channel characteristics favoring double-edge pulsewidth modulation

M-ary pulsewidth modulation (M-PWM) and double-edge pulsewidth modulation (DPWM) are compared to non-return-to-zero (NRZ) modulation in bandwidth-limited channels. DPWM features spectral characteristics that concentrate energy at lower frequencies compared to NRZ for a given data rate. Here, channel characteristics are studied that favor DPWM transmission. Each modulation format is compared at 10 Gb/s over two different electrical channels to study the signal integrity with respect to a fixed data rate and fixed minimum pulsewidth.
