Abstract: There are provided a turbo decoding system of a CDMA mobile communication terminal, a transmission power control method, and a CDMA mobile communication terminal in which interference in the other users is suppressed by not increasing the transmission power of a base station to a value over the necessary value and excessive repetitive processing is prevented in the turbo decoding section to reduce consumption power. There are disposed a BLER measuring section 10 to measure BLER as reception quality for each number of decoding bits on the basis of a CRC judge result after an error correction by the turbo decoding section 4 and an outer loop power control and iteration control section 11 to control transmission power of a base station and to control the iteration count of turbo decoding on the basis of the reception quality of each number of decoding bits.
