Method and apparatus of an architecture to switch equalization based on signal delay spread
Abstract:
The 60 GHz channel between the transmitter and receiver can have AWGN characteristics allowing a Time Domain Equalizer (TDE) to be used at the receiver instead of a Frequency Domain Equalizer (FDE). The complexity of performing matrix inversion on a received signal is reduced when directional antennas are used in a 60 GHz system. Incorporating the TDE in place of the FDE saves almost an order of magnitude in power dissipation. For portable units, such a savings is beneficial since the battery life can be extended. The signal quality of wireless channel is based on the characteristics of the received signal to switch the equalization operation from a system performing FDE to TDE and vice versa. The receiver adapts to the received signal to reduce the power dissipation of the system.
