Abstract(in English) | This paper proposes the channel parameter estimation technique by the conjugate gradient method. Conventional search-based methods such as SAGE suffers from poor resolution of the antenna radiation pattern and enormous computational complexity, which leads to large errors and high residual during estimation. However during the implementation of the conjugate gradient method, a continuous and differentiable antenna radiation pattern in both spatial domain and frequency domain is necessary. This paper will discuss the conversion from a discrete radiation pattern into a continuous one using spherical wave function (SWF) in minority. This research is expected to reach an improvement of the estimation accuracy and an acceleration of the estimation process. |
