摘要： Methods and apparatus are described for reducing memory storage cells in a turbo decoder by storing only half the state metrics generated during a scan process. States associated with each bit transmission may be divided into couples and only one state from every state couple may be stored. In one example embodiment, only the state metric for a losing state of every state couple is saved, along with a single bit, e.g., 1 or 0, indicating whether the upper state or lower state of the state couple was the winner. The winning state may be reconstituted at a later stage. In this manner, for a code rate 1/3 and constraint length 3 turbo code, instead of storing 8*10=80 bits of state metrics for each systematic bit, only (4*10)+(4*1)=44 bits of scan state metrics data need be stored, a savings of nearly 50% regardless of the transistor technology used.
摘要翻译：描述了用于通过仅存储在扫描处理期间生成的状态度量的一半来减少turbo解码器中的存储器存储单元的方法和装置。与每个位传输相关联的状态可以被划分为对，并且可以仅存储来自每个状态对的一个状态。在一个示例实施例中，仅保存每个状态对的丢失状态的状态度量，以及指示状态对的上部状态或较低状态是否为赢者的单个位，例如1或0。获胜状态可以在稍后阶段重新组建。以这种方式，对于码率1/3和约束长度3 turbo码，代替仅存储每个系统比特的8×10 = 80比特的状态度量，只有（4 * 10）+（4 * 1）= 44比特的扫描状态度量数据需要存储，节省近50％，而不考虑使用的晶体管技术。

摘要： Aspects of the disclosure can provide a method and an apparatus to decode a data stream based on multiple transmissions with efficient usages of storage and power resources. The method for decoding can include receiving a first plurality of encoded code blocks corresponding to a first transmission of a transport block, decoding the first plurality of encoded code blocks into decoded code blocks, error detecting the decoded code blocks, and storing a decoding history of the decoded code blocks. Further, the method can include receiving a second plurality of encoded code blocks corresponding to a retransmission of the transport block. The second plurality of encoded code blocks can map the first plurality of encoded code blocks, respectively. The method can selectively decode a subset of the second plurality of encoded code blocks based on the decoding history. In addition, the method can include storing soft bits for code blocks that failed decoding. The soft bits can be a combination of soft bits from multiple transmissions. The memory size for storing the soft bits can be reduced by dynamically freeing memory space associated with successfully decoded code blocks.
