Title: Enhanced automatic gain control mechanism for timeslotted data transmissions.
Inventor: LOUIS J GUCCIONE
IPC: H03G3/00
Filed: 2004-03-12
Abstract: An automatic gain control (AGC) method according to the present invention applies an initial gain by a digital AGC circuit in a timeslot is determined using a final calculated gain from the same timeslot in the previous frame together with an offset factor.
