System and method for channel estimation

A system, comprising:

• a radio;
• and
• one or more processors;
• and
• a memory storing instructions which, when executed by the one or more processors, cause performance of:
• calculating, by a receiver, a first channel estimate, at an nth point in time, the calculating comprising calculating an (n+D)th state vector, the (n+D)th state vector corresponding to a channel history at an (n+D)th point in time, D being a positive integer;
• performing signal processing of a received signal, based on the first channel estimate, to generate processed data;
• and
• transmitting the processed data to a data consumer,
• the (n+D)th state vector comprising elements from p update intervals,
• the first channel estimate at the nth point in time comprising an element for each of k subcarriers, k being a positive integer, and
• the (n+D)th state vector having fewer than kp(D+1) elements.
