Abstract:
A method for operation of a modem system which demodulates data bursts from a plurality of remote sites using stored channel parameters for each remote site, the method comprising:receiving a data burst from a current remote site; determining a next remote site which will transmit a next data burst; determining attenuation levels and equalizer tap values for the next remote site based on a previous burst from the next remote site; determining an equalizer phase error from the determined equalizer tap values for the next remote site; replacing attenuation levels and equalizer tap values for the current remote site with the determined attenuation levels and equalizer tap values for the next remote site in an equalizer once the burst from the current remote site is completed; storing the replaced attenuation levels and equalizer tap values for the current remote site for use with a subsequent burst from the current remote site; receiving the next burst from the next remote site; determining an initial phase and an initial gain for the received next burst from the next remote site; and demodulating the received next burst from the next remote site using the determined initial phase, initial gain, and equalizer phase error.
