WebThe detection technique is based on a channel shortening algorithm and allows for group detection of a subset of the users via MLSE. This paper presents a multiuser detector that performs close to the optimum MLSE while drastically reducing the decoding complexity and allows for group detection of a subset of the users via MLSE. WebMar 1, 2012 · Channel shortening is used in OFDM systems in order to reduce the length of the channel impulse response h to less than ν + 1, where ν is the GI size. Hence, the objective is to find an equalizer filter w such that the effective channel c = h ∗ w has a maximum of ν + 1 successive non-zero taps.

WebFeb 1, 2024 · A channel delay spread larger than the cyclic prefix (CP) creates inter-carrier/symbol interference (ISI/ICI) in orthogonal frequency-division multiplexing (OFDM). Recent interests in low-latency applications have motivated the usage of shorter OFDM symbols where one can either downscale the CP at the cost of interference, or maintain … WebChannel Shortening Filter In order to reduce the eeective channel memory, the received signals y (j) k , j = 1; :::;nR, are ltered by nRs FIR lters, which have the structure shown in Figure 4.Each ... cheap flat leather sandals
