Novel receiver signal processing for interference cancellation and equalization in cellular TDMA communication
نویسندگان
چکیده
A space-time processing scheme is proposed for TDMA based cellular/PCS communications that cancels co-channel interference while simultaneously equalizing the desired signal. This is achieved through processing of a training signal designed from a PN code. At the receiver, the symbol waveform is built up above the noise and interference through correlation with a sampled waveform designed to exploit the PN code. From this built up signal, interference canceling beams are formed along with estimates of the initial equalizer coe cients. Then a decision directed algorithm is applied to track variations in the multipath channel. Simulations involving three-ray multipath are presented demonstrating the e cacy of the method.

Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

In impulse radio ultra-wideband (IR-UWB) systems where the channel lengths are on the order of a few hundred taps, conventional use of frequency-domain (FD) processing for channel estimation and equalization may not be feasible because the need to add a cyclic prefix (CP) to each block causes a significant reduction in the spectral efficiency. On the other hand, using no or short CP causes the ...

In this paper, we adress the problem of the joint identification of the channel impulse responses of almost-synchronous cochannel users. This problem arises in a cellular system using the time division multiple access (TDMA) scheme where the base stations are assumed to be synchronized and the radius of the cells is limited to a few kilometers. After the partial equalization of the transmit pul...
