1. A mobile station comprising:

  • a transceiver comprising a transmitter circuit having a transmit RF filter that passes a transmit band of frequencies that is partitioned into transmit frequency channels and a receiver circuit having a receiver RF filter that passes a receive band of frequencies that is partitioned into receiver frequency channels, wherein the transmit band of frequencies comprises at least one first end channel, at least one second end channel, and interior channels between the first and second end channels, wherein the receive band of frequencies comprises at least one first end channel, at least one second end channel, and interior channels between the at least one first and second end channels; and

    baseband circuitry capable of compensating for a non-ideal RF operation of channels from the transmit and receive bands of frequencies, the baseband circuitry arranged to compensate for the non-ideal operation of said RF filters of at least one of the at least one first and second end channels of the transmit and receive bands of frequencies and arranged to not compensate for the non-ideal RF operation of said RF filters of any of the interior channels of the transmit and receive bands of frequencies.
