摘要： A communication unit for performing soft-decision demodulation comprises a receiver that receives a transmitted signal conveying a first set of bits comprising k bits selected from a set of 2k possible signals. A demodulator comprises a bank of 2k correlators that detects a transmission of each possible transmitted signal, and outputs 2k magnitudes of correlator outputs, based on the detected possible transmitted signals, as a first set of inputs. A-de-mapper circuit receives the first set of inputs and determines derived from a plurality of aggregated correlator output magnitude distributions of the first set of inputs, wherein the plurality of aggregated correlator output magnitude distributions is fewer than 22k; and calculates therefrom a first set of aposteriori soft bits comprising k soft bits. In this manner, high quality soft-decisions can be obtained in a robust and practical manner.

摘要： An apparatus and method for optimizing the performance of satellite communication system receivers by using the Soft-Input Soft-Output (SISO) BCJR (Bahl, Cocke, Jelinek and Raviv) algorithm to detect a transmitted information sequence is disclosed. A Sliding Window technique is used with a plurality of reduced state sequence estimation (RSSE) equalizers to execute the BCJR algorithm in parallel. A serial data stream is converted into a plurality of data blocks using a serial-to-parallel converter. After processing in parallel by the equalizers, the output blocks are converted back to a serial data stream by a parallel-to-serial converter. A path history is determined using maximum likelihood (ML) path history calculation.

摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A performance of the existing sliding-window superposition coding (SWSC) is degraded when a wireless channel state is changed due to a large scale fading and a small scale fading. In addition, the performance of the existing SWSC is degraded when channel state information at a receiver is different from that of the real channel. To resolve these problems, a transmitter applies an accurate data transmission rate suitable for a channel state. Therefore, a receiver applies an adaptive SWSC and to reduce a block error rate (BLER) and a hybrid automatic repeat request (HARQ) overhead of the receiver. In addition, to resolve wireless channel state change due to large and small scale fading, the transmitter may use the adaptive transmission method.
摘要翻译：本公开涉及用于支持超过第四代（4G）通信系统（例如长期演进（LTE））的更高数据速率的前5代（5G）或5G通信系统。当无线信道状态由于大规模衰落和小规模衰落而改变时，现有的滑动窗口叠加编码（SWSC）的性能下降。此外，当接收机的信道状态信息与真实信道的信道状态信息不同时，现有的SWSC的性能下降。为了解决这些问题，发射机应用适合于信道状态的精确数据传输速率。因此，接收机应用自适应SWSC并减少接收机的块错误率（BLER）和混合自动重传请求（HARQ）开销。此外，为了解决由于大小衰落衰落引起的无线信道状态变化，发射机可以使用自适应传输方法。
