The retransmission packet capture system under wireless multiple-service communication environment using a turbo decoding

摘要

A "hybrid" ARQ system within a multiple access wireless communications environment is provided for recombining ARQ retransmission signals with information obtained from corresponding previously failed transmissions of the same signal which had been sent and received within the air interface. Forward Error Correction (FEC) is implemented within an ARQ environment by using whatever acquired information has been previously obtained from Rake processed transmitted and retransmitted signals and trying to correct the information by combining the signals and without retransmission. In a second preferred embodiment of the present invention, Turbo encoded transmitted information is only partially re-transmitted by the transmitter in order to achieve a successful transmission.
