Examples
- The computer simulation results verify the validity of two adaptive algorithms applied to circular array . the algorithms are least square based on qr decompose ( qrd - ls ) and sampling matrix inversion based on qr decompose ( qrd - smi ) . then we apply circular array with wideband signal
其次,验证了基于qr分解的最小二乘算法( qrd - ls )和基于qr分解的采样矩阵求逆方法( qrd - smi )两种自适应算法在均匀圆阵中的有效性。 - Since the filtering vector is needed in qrd - rls and qrd - brls , the parallelism of qr decomposing will be impeded slightly . the inverse qr decomposion ( iqrd ) scheme for brls algorithm is proposed in this dissertation to enhance the parallelism , the systolic array structure for iqrd is proposed to calculate the algorithm in parallel
鉴于码辅助最优滤波需要求解滤波权值矢量,此时qr分解的计算并行性不如逆正交三角分解( iqrd ) ,本文提出了基于iqr分解的brls算法,给出了iqrd - rls / brls的脉动阵列并行计算结构。 - Dbf algorithms for 2d planar array based on the algorithms for 1d array are discussed in this paper . the author ' s main contributions include research of the adaptive digital beamforming algorithm , which control both amplitude and phase of each array element : diagonal loading qrd - smi algorithm . research of two phase - only dbf algorithms : small phase perturbation restriction algorithm and maximum gain of the expected direction restriction algorithm
