App-Note :: Using a Wideband AWG to Optimize Data Throughput with Multi-Level Signaling Techniques.

Increasing the data throughput on high-speed digital interfaces can be accomplished in at least three ways:

  • Using multiple parallel signals
  • Increasing the symbol rate
  • Using higher order modulation schemes that carry more than 1 bit per symbol (such as NRZ)

Traditionally, #1 and #2 are used because NRZ data transmission is very well understood and can be realized in a cost-effective way, both on the transmit side as well as the receive side. However, there are limitations.

Using a higher order modulation scheme has the advantage that more than 1 bit per symbol can be transmitted without increasing the bandwidth requirement. The spectrum plots below show that the data rate can be doubled without increasing the occupied bandwidth.
