The invention provides a method for channel estimation enhancement and a wireless apparatus. The method for channel estimation enhancement comprises the steps of receiving high efficiency frames at awireless communication network via the wireless apparatus, wherein the high efficiency frames include conventional lead codes and high efficiency lead codes, the conventional lead codes including first training fields and the high efficiency lead codes including signal fields and second training fields; executing channel estimation based on the first training fields for first channel conditions and second training fields for second channel conditions; decoding beam change indicators in the signal fields and judging whether there is beam change between the first channel conditions and the second channel conditions; if the beam change indicators indicate no beam change, obtaining an enhanced channel response matrix based on the first training fields and the second training fields to executechannel estimation enhance
