    Abstract: An arrangement (300) and method, for iterative channel impulse response estimation in a system such as a GSM/EDGE system employing a transmission channel, by: producing (310) from a received signal (y) a channel impulse response estimate signal (p); and producing (320) from the received signal (y) a noise estimate signal (w) which is iteratively fed back to improve the channel impulse response estimate signal (p). The noise estimate signal comprises a matrix (w) respresenting the inverse of noise covariance; the matrix may be calculated at each iteration or may be selected from predetermined values corresponding to statistics of expected noise. This provides the advantages of reduced complexity, independence of the equalization method used to produce the channel impulse response estimate signal, and consequent performance improvement.

    Abstract: An improved turbo code based incremental redundancy includes a first step (102) of puncturing a data stream for a first transmission to provide a set of first unpunctured trellis sections. A next step (104) includes puncturing a data stream for a second transmission to provide a set of second unpunctured trellis sections. A next step (106) includes incremental redundancy combining the first and second transmissions of the trellises to provide non-adjacent first and second unpunctured trellis sections. The above arrangement results in a uniform distribution of punctured and unpunctured bits to provide lower errors.

    Abstract: A method of enchancing a communication capability of a communication unit (112), operating in a communication system (100) that facilitates communiction to and/or from a plurality of communication units, is described. The method includes the step of operably coupling a first communication unit (112) to one or more neighbouring communication units (114, 116) such that said communication unit is able to utilise at least one operational capability of one or more of its neighbouring communication units to enchance communication to and/or from said first comunication unit.This provides the advantage that a collective use of neighbouring communication units, for example formed in an aggregate group, provide a more reliable uplink and/or downlink communication kink without using more network resources. In particular, the transmitting/receiving communication unit is able to utilise functionality in neighbouring communication units to which it can be operably connected. Furthermore, the wireless or wired communication link efficiency is improved and higher data rate throughput can be realized.
