Channel estimation for OFDM communication systems including IEEE 802.11A and extended rate systems

摘要: Channel estimation techniques are provided for a receiver of wireless communication system using orthogonal frequency division multiplexing (OFDM), including legacy 802.11a and various extended rate systems. Training signals received from one or more receive antennas. An estimated channel impulse response is computed the training by reference to sequence. The truncated in time domain based on power noise data. tracking may also be implemented correct variations over transmission packet.
