This paper deals with data-aided (DA) carrier frequency and time offset synchronization schemes for a transmultiplexer (TMUX) using an exponentially modulated filter bank (EMFB). In filter-bank multicarrier (FBMC) systems like orthogonal frequency division multiplexing (OFDM), accurate synchronization schemes must be achieved because of interference produced by synchronization errors. We offer two...
This work considers adaptive subchannel equalization in Exponentially-Modulated Filter Bank (EMFB) transmultiplexers (TMUX) when the channel is highly frequency selective. Using higher order sub-equalizers, improves the performance in this condition but convergence rate of adaptive algorithms decreases by increasing their order. Recently, Fine-Coarse (FC) algorithm was proposed for improving the convergence...
This paper presents a novel low power high linear sub-harmonic mixer for direct-down conversion receiver, in which an inductive connection between RF and LO stages is used to improve the linearity and enhance the gain of mixer. A comparison is done between two circuits for two possible conditions, high gain medium linearity (HGML) and high linearity medium gain (HLMG), and recently published works...
