Abstract: A time division multiple access cellular radio telecommunications network is disclosed, in which physical channels may be reused in the same cell. Reused channels on the up link are differentiated by a time shift between them. Same cell reuse (SCR) can thus be implemented in a TDMA (GSM) system without assigning different signatures to SDMA users sharing the same physical channel.

Abstract: A method and apparatus for estimating channel impulse response and data in a signal transmitted over a channel in a communication system. The channel impulse response is estimated uses correlative channel sounding, and then, using the estimated channel impulse response, the data in the signal is estimated. The output is then fed back to the channel impulse response estimator and the channel impulse estimation is repeated. The data estimation and channel impulse response estimation may be iterated a number of times.

Abstract: The invention includes method and apparatus for estimating channel impulse response and data in a signal transmitted over a channel in a communication system. The channel impulse response is estimated and then, using the estimated channel impulse response, the data in the signal is estimated. The output is then fed pack to the channel impulse response estimator and the channel impulse estimation is repeated. The data estimation and channel impulse response estimation may be iterated number of times. The channel impulse response estimating step uses correlative channel sounding.

Abstract: Apparatus and method for iteratively decoding a signal are provided. The apparatus includes a central pool of resources for iteratively decoding signals. The central pool may run a plurality of iterative decoding processes, each process being allocated to a signal processing unit upon request and depending upon resource availability.
