1. A partial echo cancellation duplexing system, comprising:
partial echo cancellation duplexing circuitry configured to adjust a data rate of an upstream transmission or downstream transmission based on an upstream crosstalk effect and a downstream crosstalk effect, respectively; and
channel estimation circuitry configured to determine at least one of the upstream crosstalk effect and the downstream crosstalk effect based on transmissions of an upstream data frame and a downstream data frame, respectively, wherein one or both of the upstream data frame and the downstream data frame include a synchronization symbol or a quiet symbol in a first symbol position, and the channel estimation circuitry is configured to determine at least one of the upstream crosstalk effect and the downstream crosstalk effect based on the synchronization symbol.
