Abstract: A receiving system for estimating symbol timing in a feed-forward manner comprises: a matched filter for receiving baseband signals and dividing them into real and imaginary numbers; a symbol timing estimator for receiving signals from the matched filter and estimating symbol timing using variables; a storage unit for storing the variables and outputting them according to requests of the symbol timing estimator; an interpolator for receiving a symbol timing estimate from the symbol timing estimator, and interpolating symbol-reading timing of the baseband signal; a delayer for delaying the baseband signal input to the interpolator; an RF/IF signal processor for receiving RF signals and performing RF/IF signal processing; and a baseband converter for converting the signal output from the RF/IF signal processor into baseband signals, and outputting them to the matched filter.

Abstract: A dynamic resource allocation apparatus and method for assigning timeslot in a return channel in multifrequency time division multiple access MF-TDMA in order to have a maximum throughput is disclosed. The apparatus includes: resource request amount collection unit for accumulating a requested resource amount corresponding to each of terminals during a super-frame period; resource request amount processing unit for dividing an accumulated requested resource amount by the number of frame pairs in a super frame and storing a sum of a result of dividing and rounding up a remain of the division to a nearest integer as a request amount of each corresponding terminal ; and resource allocation unit for deciding a time slot allocated at each of terminals corresponding to a frame pair based on optimal allocation amount, which is decided based on the request amount by the requested amount processing unit.
