A network device including a first feedback module and a first calibration module. The first feedback module generates a first transmission schedule, which include (i) a first subcarrier schedule to determine an order of transmitting subcarriers and (ii) a first matrix map, and which is transmitted to a link partner. The first calibration module transmits a first set of training signals to the link partner, receives a first set of channel state information (CSI) (i) generated by the link partner based on the training signals and (ii) transmitted by the link partner according to the first transmission schedule, and generates a first CSI matrix based on the first set of CSI and the first matrix map. The first calibration module is configured to (i) generate the same first set of training signals for each of the subcarriers and (ii) receive the first set of CSI for each of the subcarriers.
