... compensation of the transmitter and receiver IQ imbalance from the compensation of the channel dis- tortion. Once the IQ imbalance parameters are known, a standard channel equalizer can then be applied ... Imbalance and Channel Distortion Compensation. In the case of only transmitter IQ imbalance and no receiver IQ imbalance (G ra [l] = 1, G rb [l] = 0), we can decouple D tot [l] as f...

The pigeon has enough communication ability to know the arrivals of messages on ... the messages whenever they are available. This approach can be viewed as an on- demand strategy. However, there is a big disadvantage of the on- demand strategy in the scenari...
