Described herein are a technique, method, device and system related to reducing memory requirements and complexity in receivers. According to the present disclosure, the capability to request precoded ACE symbols is added to receivers in a mode under the g.hn MIMO standards that uses precoding to enhance the capacity of links. Using precoded ACE symbols, memory requirements for the receiver can be reduced as it is not necessary for the receiver to save the precoder coefficients. Additionally, the frequency of updates required for the precoding coefficients can be reduced by adapting the MIMO decoder using the precoded ACE symbols as reference symbols.
