  givens rotation
We observe that the classical Givens' rotation in the real and in the complex case is itself a quaternion using an isomorphism between certain (2×2) matrices and R4 equipped with the quaternion multiplication.
      
Comparisons to the existing known methods, such as Householder transformation and Givens rotation, are also given.
      
Specifically, the Householder transformation outperforms the Givens rotation and the modified Gram-Schmidt methods in numerical stability under finite-precision implementations, as well as requiring fewer arithmetical operations.
      
Actually, one additional Givens rotation for each regularization parameter is necessary for the diagonalization of the subproblem matrix.
      
Thus, the orthonormal matrix Qk is composed of the products of the Givens rotation matrices.

A receive least squares (RLS) lattice adaptive algorithm is developed for a cmsstalk-resistant adaptive noise canceller (CTRANC). The derivation of the algorithm is based solely on numerical robust Givens rotations, which have superior numerical property and better modular structure performance. Becaase square-root operations are not included, the proposed algorithm is very suitable for the implementation ed a conventiona digital signal procossor(DSP). An array implementation scheme is discussed and a high performance ANC can be realixzed by increasing the computing tiee slightly. Simulation results show that the convergence speed is much faster than that of the ekishng least mean square (LMS) algorithm.
