20150244450 | ECHO CANCELLATION IN COMMUNICATION TRANSCEIVERS - A method includes, in a transceiver ( | 08-27-2015 |
20140079163 | TIMING RECOVERY FOR LOW ROLL-OFF FACTOR SIGNALS - A method includes receiving a signal, which carries data in a sequence of symbols that are modulated in accordance with a pulse shape and transmitted in accordance with a timing clock. The received signal is filtered with a matched filter whose response is matched to the pulse shape of the symbols, to produce a filtered signal. The timing clock is initially recovered from the received signal prior to filtering with the matched filter. Upon meeting a predefined condition, a switch is made to recover the timing clock from the filtered signal after filtering with the matched filter. The symbols are demodulated using the recovered timing clock, so as to reconstruct the data. | 03-20-2014 |
20140075258 | ITERATIVE RECEIVER LOOP - A method includes receiving a signal, which carries data that is encoded with an Error Correction Code (ECC), and correcting the received signal with an adaptive receiver loop. Soft input metrics for the data are computed over the corrected signal. The ECC is decoded using a decoder, which estimates soft output metrics based on the soft input metrics, by operating the decoder in an alternating pattern of external iterations that update one or more of the soft input metrics based on one or more of the soft output metrics, and internal iterations that update the soft output metrics but not the soft input metrics. The adaptive receiver loop is adjusted in a schedule that is defined relative to the pattern of the external and the internal iterations of the decoder. | 03-13-2014 |
20120214524 | SATELLITE RECEIVER WITH INTERFERING SIGNAL CANCELLATION - A method for communication includes receiving a Radio Frequency (RF) channel containing a desired signal conforming to a first air interface and an interfering signal conforming to a second air interface. A first receiver configured for the first air interface and a second receiver configured for the second air interface are synchronized to a common frequency and timing reference. While the first and second receivers are synchronized, the desired signal is decoded from the RF channel using the first receiver to generate a first output, the interfering signal is decoded from the RF channel using the second receiver to generate a second output, and the desired signal is reconstructed while suppressing the interfering signal by jointly processing the first and second outputs. | 08-23-2012 |
20120079341 | ITERATIVE DECODING OF LDPC CODES WITH ITERATION SCHEDULING - A method includes accepting modulated symbols, which carry bits of a code word of a Low Density Parity Check (LDPC) code, and computing respective soft input metrics for the bits. The code word is decoded using an iterative LDPC decoding process that includes selecting, based on a predefined criterion, a number of internal iterations to be performed by an LDPC decoder ( | 03-29-2012 |
20120039247 | FRONT-END FOR SATELLITE COMMUNICATION - A communication method includes operating a communication unit ( | 02-16-2012 |
20110188550 | HIGH-PERFORMANCE FASTER-THAN-NYQUIST (FTN) SIGNALING SCHEMES - A method for communication includes modulating data to produce a series of symbols defined in a signal space. The symbols are pulse-shaped using a given pulse shape. A signal, which includes a sequence of the pulse-shaped symbols ( | 08-04-2011 |
