Multiple-Input Multiple-Output (MIMO) systems are very sensitive to carrier phase offset. In this paper, challenges regarding the provision of phase offset in orthogonal space time block codes (STBC) coded MIMO systems over Rayleigh fading channels are addressed. We develop a novel robust phase offsets estimation algorithm for MIMO systems based on STBC codes. Simulation results prove that the proposed...
An algorithm is presented for blind phase offset estimation for signals with quadrature amplitude modulation. The algorithm is based on a circular harmonic expansion of log-likelihood function (LLF). Retaining one or two most significant terms in this series gives a harmonic or biharmonic circular decomposition of the LLF, this approach leads to notable improvement of the estimation quality comparing...
In [1] we presented a new algorithm for blind phase offset estimation for signals with quadrature amplitude modulation (QAM). The algorithm is based on a circular harmonic expansion of log-likelihood function (LLF). Retaining one or two most significant terms in this series gives a harmonic or biharmonic circular decomposition of the LLF, this approach leads to notable improvement of the estimation...
