- Abstract
- In this paper, we propose joint phase noise and channel estimation techniques that are applicable to any arbitrary reference signal configurations. In the orthogonal frequency division multiplexing (OFDM) system operating in mmWave and sub-THz bands, the inter-carrier interference (ICI) caused by the phase noise is a critical issue because of the severe phase noise in high frequency bands. The phase noise estimation algorithms in the existing works are applicable only to the full or block-type reference signal configurations. In this paper, we formulate a generalized estimation problem applicable to any arbitrary reference signal configurations, and suggest the least squares (LS), majorization-minimization (MM), generalized least squares (GLS), and linear minimum mean squared error (LMMSE) estimators to solve the problem. The performance of the proposed algorithm is evaluated with the phase noise model for the sub-THz bands. IEEE
