Stochastic Estimation of MIMO Detection Error Caused by Low-Bitwidth QR Decomposition
In this paper, we propose a new approach to justify a roundoff error impact on the accuracy of the linear least squares (LS) solution using QR decomposition. This decomposition is widely employed to invert a matrix in the linear detector of the multi-user multi-antenna receiver. Compared to existing...
