- W3000433030 abstract "In this paper, we propose a One-Shot Blind Channel Estimation (OSBCE) system, originally developed for Single-Input Single-Output Orthogonal Frequency Division Multiplexing (SISO-OFDM) [1], to Multiple-Input Multiple-Output OFDM (MIMO-OFDM) systems in two main variations, namely ‘Mode 1’ and ‘Mode 2’. Mode 1 utilizes a coding scheme in order to separate the symbols used in the OSBCE structure per antenna, while Mode 2 depends on using nulling to eliminate cross talk between the antennas. The two developed modes can be structured in different variations in response to the channel conditions as a function of the Euclidean distance between the symbols used in the OSBCE structure. The OSBCE for MIMOOFDM systems is benchmarked against the pilot-based channel estimation scheme, and its performance is reported mainly for the two different proposed modes. It is shown the proposed OSBCE Mode 1 for MIMO-OFDM systems trades complexity and spectral efficiency for better estimation performance compared to Mode 2 with the same number of receive antennas. Still, both OSBCE modes can achieve reliable channel coefficients, with similar complexity to that of the pilot-based system given enough receive antennas are used." @default.
