KRONECKER APPROXIMATION AND SCALAR QUANTIZATION OF TRANSMIT WEIGHT VECTORS

摘要

Communication systems may benefit from various techniques for the efficient communication of channel characteristics. For example, wireless communication systems may benefit from the use of Kronecker approximation and scalar quantization of channel eigenvectors. A method can include approximating, using a Kronecker approximation, an eigenvector of a set of eigenvectors for a channel of a user equipment via a least-squares approach to produce a reduced-dimension vector. The method can also include quantizing the reduced-dimension vector using scalar quantization to produce a quantized representation. The method can further include transmitting the quantized representation to a base station.
