APPARATUS AND METHOD FOR CARRIER PHASE ADJUSTMENT FOR MULTIPLE ACCESS COMMUNICATION SYSTEMS WITH MULTI-PACKET RECEPTION CAPABILITY

摘要

PURPOSE: An apparatus and a method of controlling a carrier phase for multiple access communication in an environment of receiving a multi-packet are provided to control a carrier phase by estimating the carrier phase from a signal transmitted from a plurality of transmission nodes. CONSTITUTION: An apparatus of controlling a carrier phase is divided into a transmitting unit(100) and a receiving unit(200). The transmitting unit includes a plurality of source node(110-1-110-N). Each transmission node respectively comprises encoders(111-1-111-N) and mappers(112-1-112-N). The receiving unit comprises a demapper(210), a decoder(220), a carrier phase estimating unit(230), and a phase information transmitting unit(240). A plurality of transmission nodes included in the transmitting unit respectively transmits data. The encoders encode the data.
