The apparatus includes a turbo encoder, an interleaver for interleaving symbols output from the turbo encoder according to a give rule, and a code generator for generating the quasi-complementary turbo codes by puncturing and repeating the interleaved symbols from the interleaver. Further, an apparatus decodes quasi-complementary turbo codes in the communication system. The decoding apparatus includes a code decoder for generating code symbols according to a code rate transmitted through depuncturing sub-codes of quasi-complementary turbo codes transmitted from a transmitter and soft combining the sub-codes, a deinterleaver for deinterleaving the symbols output from the code decoder, and a turbo decoder for decoding an output of the deinterleaver.

摘要： A power control method during a soft handoff in a mobile communication syste m. A mobile station communicating with a plurality of base stations at a soft handoff measures the signal strengths of forward common pilot channels received from the base stations and transmit them to the base stations sequentially. Then the base stations control the transmission power of forwa rd common power control channels according to the received signal strength measurements.
