    摘要: A dynamic tracking application for a mobile communications device is disclosed. The dynamic tracking application enters itinerary events into the mobile communications device to create an itinerary. The itinerary events are plotted on a map that can be displayed by the mobile communications device. The itinerary is then executed by calculating and storing directions to get from one itinerary event to the next itinerary event and calculating and storing estimated departure and arrival times between itinerary events. This is compared to the current time and location of the mobile communications device to further determine whether the user can arrive on time at the next scheduled itinerary event based on the calculated time and distance to the next scheduled itinerary event. If not, the user is prompted to edit the itinerary or it can be done automatically.

    摘要: A spectrum analyzer is described which comprises a mixer for mixing the conjugate complex input signal v*(t) into a base band signal x(t), and a resolution filter for narrow-band filtering the base band signal. The resolution filter has a complex, discrete impulse response using a variation parameter k0 set to compensate for the frequency overshoot determined by the group delay of the resolution filter.

    摘要: The invention concerns a method for analysing an OFDM signal (rIF(t)) transporting a series of data symbols on several orthogonal carrier frequencies, each data symbol having a useful part separated by a guard period from neighboring data symbols, with an analysing device (40) having a signal section (20) with a bandwidth (BWA) smaller than the bandwidth (BWOFDM) of the OFDM signal. The method comprises the steps of low pass filtering of the OFDM signal with a low pass filter (24) and shifting (26) the spectrum of the OFDM signal in order to obtain a frequency shifted filtered OFDM signal (r(i)), whereby the length of the impulse response of the low pass filter (24) is shorter than the length of the guard periods of the data symbols.

    摘要: A method for the incrementation of counter statuses in memory cells, which are arranged respectively in rows and columns of a first memory adds a “1” to the memory content of a memory cell of a second memory, which corresponds to the memory cell at the start of a sequence of memory cells to be incremented in a row or column of the first memory in the case of every incrementation of a sequence of memory cells of the first memory, and adds a “−1” to the memory content of a memory cell of the second memory, which corresponds to the memory cell immediately following the memory cell at the end of the sequence of memory cells to be incremented associated with the start of the sequence, in the case of every incrementation of a sequence of memory cells of the first memory. It then recursively adds the memory content of a memory cell arranged in a row or column of the second memory to the memory content of the memory cell arranged in the next lower row or column of the first memory and stores the result of the addition in the memory cell arranged in the row or column of the first memory.

    摘要: A method for shared estimation of parameters (ε, φ, |C1|, C0, α, Δω) is described, which together with an error vector e(k), describe the connection between a digitally modulated reference signal inputted to a transmission channel and a received receiver signal z(k) which is at an end of the transmission channel. The method includes the following steps: forming the error vector e(k) in dependence of the parameters (ε, φ, |C1|, C0, α, Δω), a reference signal s(k), and the receiver signal z(k); linearizing the error vector e(k); substituting a real parameter of the linearized error vector through components of a estimation vector, wherein a substituted error vector is produced; inserting the substituted error vector into the cost function; and determining the estimation vector through gradient development of the cost function and subsequently setting the gradient to zero.
