摘要： 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.

摘要： A novel apparatus for and method of estimating the cable length of an active network link. The cable diagnostics mechanism of the invention is particularly suited for use in estimating the length of Ethernet network between two edges when the link is active, i.e. data is being transmitted in both directions simultaneously and the transmission of test pulses is not possible. The cable length estimation mechanism of the present invention is based on a well-known property of the spectrum of the insertion loss of the cable, namely, the linear relationship between the attenuation of the cable at a given frequency in decibels and the cable length. Information characterizing this relationship is extracted and used to determine the length of the cable.

摘要： A communication method includes operating a communication unit (60, 124), which demodulates radio signals in accordance with a first air interface and applies at least one upper-layer process to the demodulated signals. A signal is received and demodulated in accordance with a second air interface, different from the first air interface. The demodulated signal is input to the communication unit so as to cause the communication unit to apply the upper-layer process to the signal that was demodulated using the second air interface, while superseding the first air interface.

摘要： 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 (104A . . . 104C) transmitted at a symbol rate that is higher than a Nyquist rate defined for the given pulse shape, is transmitted to a receiver (40). Prior to pulse-shaping the symbols, Inter-Symbol Interference (ISI) in the signal is pre-compensated for by applying a lattice precoding operation to the symbols. The lattice precoding operation confines the symbols to a predefined volume (110) in the signal space and is computed independently of any feedback from the receiver.

摘要： A method and system for performing Multiple-input Multiple-Output (“MIMO”) detection that reduces complexity by decomposing MIMO detection problem into two less complex problems, Candidate List generation and Interference Cancellation (“CLIC”). Embodiments of the CLIC framework parse an N element channel output into a first set containing S elements and a second set containing N-S elements. A first list of candidate vectors is generated from the first set of elements. A set of interference cancelled elements is generated by using the first list of candidate vectors to cancel interference from the second set of elements. A second list of candidate vectors is generated from the set of interference cancelled elements. A minimum cost is computed for each bit of the candidate vectors and from the costs a log-likelihood ratio is computed.

摘要： 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 (84) in the process, performing the selected number of the internal iterations using the LDPC decoder so as to estimate decoded bits and soft output metrics indicative of the input bits based on the soft input metrics, performing an external iteration that updates one or more of the soft input metrics based on one or more of the soft output metrics produced by the LDPC decoder, and repeating at least one of the internal iterations using the updated soft input metrics.

摘要： 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.
