摘要： Detection of errors in the results of turbo decoding is performed while decoding is being repeated. If absence of errors is detected, the results of decoding are output, even though repetition of the decoding operation is in progress, and further decoding is discontinued. Further, the number of times errors are detected in decoded results when decoding has been performed a set number of times is monitored and the decoding operation is executed again if the number of times errors are detected is equal to or less than a set value. Further, one of first and second decoded results output from first and second elementary decoders that construct a turbo decoder is selected as appropriate and is then output.
摘要翻译：在解码重复时执行turbo解码结果中的错误检测。如果检测到没有错误，则即使正在进行解码操作的重复，也输出解码结果，并且中断进一步的解码。此外，如果检测到错误的次数等于或小于设定值，则监视当已经执行了设定次数的解码时在解码结果中检测到错误的次数并再次执行解码操作。此外，适当地选择构成turbo解码器的第一和第二基本解码器输出的第一和第二解码结果中的一个，然后被输出。

摘要： The invention relates to the domain of turbo decoders. Such a decoder comprises a first decoder (14) and a second decoder (16), each decoder being able to calculate extrinsic output data from extrinsic input data coming from the other decoder. The decoding circuit according to the invention comprises a single memory (31) for storing the extrinsic data. When a decoder calculates an extrinsic output data from an extrinsic input data coming from the other decoder and stored in the single memory at a certain address, this extrinsic output data is then written at this same address.

摘要： An efficient turbo decoder. The disclosed turbo decoder includes a first mode of operation in which the turbo decoder uses a first functional loop. The first functional loop includes a memory bank, a read interleaver, a first multiplexer (MUX), a RAM file, a log-MAP decoder, a write interleaver, and a second MUX. The disclosed turbo decoder further includes a second mode of operation in which a second functional loop is used. The second functional loop includes the memory bank, the first MUX, the RAM file, the log-MAP decoder, and the second MUX. The memory bank is a dual port extrinsic memory.
