Patent number: 8891698Abstract: A scheme determines the first significant path (FSP) of a received multipath signal, from data defining the relative delay and the amplitude of the individual signal paths occurring in a series of time frames. The scheme includes filtering the data to spread the signal paths, performing a persistence test between frames to reject spurious signal paths, combining the energy of the signal paths in a frame, applying a test to determine the time at which the combined energy satisfies a criterion, and selecting the FSP dependent on that time. The combined energy may be evaluated within a sliding window, and the position of the window within the frame determined that maximizes the combined energy. Alternatively, the combined energy may be evaluated as the cumulative energy through the frame, and the position determined at which the cumulative energy reaches a threshold.Type: GrantFiled: December 2, 2008Date of Patent: November 18, 2014Assignee: ST-Ericsson SAInventors: Stefania Sesia, Giuseppe Montalbano, Pierre Demaj

Patent number: 8824539Abstract: An OFDM receiver for processing an OFDM received signal to perform OFDM reception in presence of Doppler effects is provided. The receiver has at least two parallel processing chains, each processing chain has a time domain windowing for processing an OFDM block. The processing consisting of the multiplication, element by element of the OFDM block, by a set of predetermined coefficients. The receiver also has a DFT block (such as FFT) for demodulating said windowed OFDM symbol into the frequency domain equivalent wherein the windowings of the at least two parallel processing chains have complementary profiles so as to avoid any loss of information throughout the OFDM sample. The invention also provides a process to be used in an OFDM receiver.Type: GrantFiled: March 11, 2010Date of Patent: September 2, 2014Assignee: ST Ericsson SAInventors: Ancora Andrea, Giuseppe Montalbano

Patent number: 8259854Abstract: The present invention relates to a receiver apparatus and method of channel estimation in a telecommunication system which provides at least two pilot sequences, and to a computer program product. Channel estimation is achieved by estimating channel taps separately for each of the at least two pilot sequences in every transmission block, and for applying estimated channel taps obtained from the estimation to at least one of a temporal and spatial filtering or combining operation to refine the channel estimate. Accordingly, temporal correlations and cross-correlations of the at least two pilot sequences are exploited without requiring knowledge of path delays and beamforming parameters.Type: GrantFiled: April 11, 2007Date of Patent: September 4, 2012Assignee: ST-Ericsson SAInventors: Ahmet Bastug, Giuseppe Montalbano

Patent number: 8005159Abstract: The present invention relates to a method for estimating a propagation channel in the presence of transmit beam-forming within a receiver, accounting for the structure of two logical channels referred as to a common channel and a dedicated physical channel (CPICH, DPCH) and based on a common structure of corresponding propagation channels, said DPCH channel comprising two sub-channels (DPDCH, DPCCH), said propagation channels being modeled as a linear superposition of a finite number of discrete multipath components following an uncorrelated-scattering wide-sense stationary model, a multipath component being characterized by a time-varying multipath complex coefficient and a delay. Use: RAKE Receiver.Type: GrantFiled: October 10, 2003Date of Patent: August 23, 2011Assignee: ST-Ericsson SAInventor: Giuseppe Montalbano

Patent number: 7941099Abstract: The estimated power levels that are used to estimate a signal-to-interference ratio (SIR) are filtered so as to minimize the mean-square error (MSE) of the estimated power estimates. First order infinite impulse response (IIR) filters are used to filter both the signal power estimates and the noise power estimates. Optionally, estimates of the average signal power and average interference power are filtered using Weiner linear prediction filters. The SIR estimates are suitable for use in a transmission channel that includes fading as well as interference, and are suitable for use in BPSK, QPSK, and other modulation systems.Type: GrantFiled: July 11, 2005Date of Patent: May 10, 2011Assignee: NXP B.V.Inventor: Giuseppe Montalbano

Patent number: 7860198Abstract: An overall SIR estimate is based on a weighted-average of different SIR estimates, wherein the weights are chosen to minimize the mean-square-error (MSE) of the overall SIR estimate. Alternatively, the overall SIR estimate is based on a selection from among the different SIR estimates, based on the expected reliability of each SIR estimate. The expected reliability of each SIR estimate may be based on the current format of the transmitted signal and/or a prior estimated SIR level.Type: GrantFiled: March 22, 2005Date of Patent: December 28, 2010Assignee: NXP B.V.Inventor: Giuseppe Montalbano
