摘要： Certain aspects of the present disclosure relate to a technique for two-step joint demapping based on sphere decoding for log-likelihood ratio (LLR) computation related to a received multiple-input multiple-output (MIMO) signal. The first step of the proposed algorithm comprises a linear minimum mean square error (LMMSE) based detection to form soft symbol estimates of symbols being transmitted. Then, the LMMSE-based soft symbol estimates can be utilized to form a set of constellation points of a stream interfering to a stream of interest. These candidate constellation points can be then subtracted (cancelled) from the received signal to improve the LLR computations of the stream of interest. After the cancellation, the maximum ratio combining (MRC) can be applied to each individual stream to form more refined soft symbol estimates as well as an effective signal-to-noise ratio (SNR) estimate. The refined outputs of the MRC can be utilized to compute LLRs of transmitted bits based on the effective SNR and the refined soft symbol estimates associated with all the candidate constellation points from the set. The LLRs of transmitted bits may be employed by a channel decoder.
摘要翻译：本公开的某些方面涉及用于基于与接收的多输入多输出（MIMO）信号相关的对数似然比（LLR）计算的球体解码的两步联合解映射的技术。所提出的算法的第一步包括基于线性最小均方误差（LMMSE）的检测，以形成被发送的符号的软符号估计。然后，可以使用基于LMMSE的软符号估计来形成干扰感兴趣的流的流的一组星座点。然后可以从接收的信号中减去（取消）这些候选星座点，以改善感兴趣的流的LLR计算。在取消之后，最大比合并（MRC）可以应用于每个单独的流以形成更精细的软符号估计以及有效的信噪比（SNR）估计。可以利用MRC的精细输出来基于与集合中的所有候选星座点相关联的有效SNR和精细的软符号估计来计算发送比特的LLR。传输比特的LLR可以由信道解码器采用。
