    • An approach for Soft-output K-Best MIMO detection comprises computing an estimated symbol vector and Log-Likelihood Ratio (LLR) values for transmitted bits. The approach includes a relevant discarded paths selection process, a last-stage on-demand expansion process, and a relaxed LLR computation process. The relevant discarded paths selection process includes analyzing the K-Best paths and discarded paths at each intermediate tree level and selecting only those discarded paths for further processing that will help in LLR computation for at least one of the transmitted bits. The last-stage on-demand expansion process includes expanding K paths at the tree level 2N T 1 (N T = number of transmit antennas) on-demand to only 2K1 lowest Partial Euclidean Distance (PED) paths at last tree level 2N T . The relaxed LLR computation scheme includes approximating LLR computations by assuming that discarded path PED is greater than or equal K-Best path PED.

    • A QRD processor for computing input signals in a receiver for wireless communication relies upon a combination of multi-dimensional Givens Rotations, Householder Reflections and conventional two-dimensional (2D) Givens Rotations, for computing the QRD of matrices. The proposed technique integrates the benefits of multi-dimensional annihilation capability of Householder reflections plus the low-complexity nature of the conventional 2D Givens rotations. Such integration increases throughput and reduces the hardware complexity, by first decreasing the number of rotation operations required and then by enabling their parallel execution. A pipelined architecture is presented (290) that uses un-rolled pipelined CORDIC processors (245a to 245d) iteratively to improve throughput and resource utilization, while reducing the gate count.
    • 用于在无线通信的接收机中计算输入信号的QRD处理器依赖于多维Givens旋转,Householder反射和常规二维(2D)Givens旋转的组合,用于计算矩阵的QRD。 所提出的技术整合了众议院反思的多维湮灭能力的好处加上常规2D Givens旋转的低复杂度性质。 这种集成通过首先减少所需的旋转操作数量,然后通过使其并行执行来增加吞吐量并降低硬件复杂性。 提出了一种流水线架构(290),它可以迭代地使用未压缩的流水线CORDIC处理器(245a到245d)来提高吞吐量和资源利用率,同时减少门数。
