Resumo:
In this work we propose exploting the received signal oversampling in order to improve the performance of blind receivers over fast fequency selective fading channels.The work focus attention on MLSE/PSP (maximum-likelihood sequence estimation/per survivor processing) receivers and statistical modeling of the channel output. A state-space model for oversampled received signal in developed from a generic continous time transmission system model. Two MLSE/PSP receiving schemes relying on this model are proposed. One of them is specially suitable for dealing with the colored noise produced by oversampling. Computer simulations were conducted in order to evaluate the performance of the proposed blind receivers. The results thus obtained show that these schemes significantly outperform the synchronous MLSE/PSP receiver (for which the sampling rate is equal to the sysmbol rate).
