Abstract: The invention relates to a passenger transportation system and method for transporting a passenger from a starting point (P1) along a passenger route to a destination (P2) by at least one transporter using a transporter route (Bnull-Bnull) which overlaps at least partially with the passenger route. The system comprises a transport service provider TSP unit (1) comprising transporter route information and served network area information and being enabled for communicating passenger position data and transporter identification data with the passenger and transporter position data as well as pick-up and release notification data with the transporter; such that the passenger route is composed of at least one section of a selected overlapping transporter route. Using said system and method is more convenient to the passenger.

Abstract: Known digital QAM modulators use sine/cosine memories and a plurality of multipliers. This can be avoided by replacing the circuitry which carries out the circular rotation of nullI(n), Q(n)nullT performed in all the QAM modulators, with a CORDIC algorithm. The invented QAM modulator is comprised of a plurality of digital rotation stages (72, 73 . . . 74) coupled in sequence. The first stage (72) receives the IIN and QIN data streams and the last stage (74) outputs a vector comprising of the orthogonal I and Q components of a digital intermediate frequency signal. Each of the rotation stages rotates an input vector applied to the stage at a predetermined elementary rotation angle, said input vector being the output vector of the previous digital rotation stage. The modulator further includes an angle computation block (710) for counting the elementary rotation angles for the rotation stages. The angle computation block is connected to the phase accumulator which receives a frequency control word (FX) and based on that word generates an input word (ZIN) applied to the angle computation block.

Abstract: The invention relates to a Rake receiver of a CDMA system using IRC. The Rake receiver comprises at least two antenna branches, at least one Rake finger, and a delay estimator. The delay estimator comprises a despreader and an allocator for selecting at least one delay, and allocating a Rake finger for processing the signal component found by informing the Rake finger of the delay found. The delay estimator further comprises: a channel estimator, an interference estimator for generating an interference signal, a weighting coefficient part for providing each antenna branch with weighting coefficients maximizing the Signal-to-Interference-and-Noise Ratio, a multiplier for multiplying the pilot part by a weighting coefficient, and an antenna branch summer for combining the despread pilot parts, received via the separate antenna branches and multiplied by the weighting coefficient, to one combined pilot signal, on which combined pilot signal the selection is based in the allocator.
