| 20100070826 | TURBO DECODER WITH EXTRINSIC INFORMATION SCALING MODULES - The invention related to a turbo decoder comprising SISO decoding modules each other interconnected in a feedback control scheme having scaling modules for applying a scaling factor to extrinsic information delivered by said SISO decoding modules. The turbo decoder comprises a selection module for adaptively selecting said scaling factor based on a number of decoding iterations of the turbo decoder. | 03-18-2010 |
| 20100159914 | RADIO COMMUNICATION SYSTEM - A transmitting station (TS), for transmitting a plurality of symbols of a data signal in a communication system, comprises a process module (PM) arranged for adding subset of the symbols of the data signal to symbols of a predetermined signal prior to proceed to transmission of the data signal. | 06-24-2010 |
| 20100241935 | TURBO DECODER WITH STAKE HERITAGE FOR DATA BLOCK REDUNDANT VERSION DECODING - An iterative decoding device (ITD) for a communication receiver comprises: i) a means (SISO | 09-23-2010 |
| 20100284493 | DOWN-SAMPLED IMPULSE RESPONSE CHANNEL ESTIMATION - A method for deriving a channel transfer function from an Orthogonal Frequency-Division Multiplex (OFDM) signal received over a channel and having unmodulated sub-carriers and sub-carriers modulated with symbols, includes the steps of sampling the received OFDM signal at a sampling rate greater than the bandwidth of the OFDM signal, deriving from the sampled OFDM signal a set of time domain coefficients representative of the channel impulse response, and deriving from a subset of the set of time domain coefficients a channel transfer function in the frequency domain. | 11-11-2010 |
| 20110055657 | METHOD AND SYSTEM FOR STOPPING EXECUTION OF A TURBO DECODER - A method for conditionally stopping execution of a turbo decoder is proposed. The decoder has elementary decoders. Each elementary decoder performs a sequence of decoding operations and is arranged to receive an input from at least one other elementary decoder. The method determines for each specific decoding operation if the sequence of elementary decoding operations of the specific elementary decoder has substantially converged or substantially diverged. The method terminates the execution of decoding operations if a number of sequences has substantially converged or substantially diverged. | 03-03-2011 |
| 20120027109 | PROCESS AND RECEIVER FOR INTERFERENCE CANCELLATION OF INTERFERING BASE STATIONS IN A SYNCHRONIZED OFDM SYSTEM - A process and receiver for canceling interference generated by a set interference base stations in a synchronized OFDM communication system and receiver in a User Equipment comprising a set of Nrx antennas. The process and receiver that cancels interference generated by a set of base stations performs OFDM demodulation on a receiver signal for each antenna of a user equipment (UE). The process and receiver also monitors each UE antenna for pilot signals generated by nearby base stations. Then the process or receiver extracts the pilot signals and establishes a list of existing base station antennas. The channel power of any interfering antennas is measured and then the Nrx-N most powerful antenna is selected. The process or receiver then performs a joint detection of the N useful Data Symbols (UDS), together with the (Nrx-N) Interfering Data Symbols (IDS) that are demodulated by demodulation blocks. Thus, after being detected, the Nrx-N most powerful IDSs can be encoded and re-injected into a cancellation loop. | 02-02-2012 |
