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 (52) configured for the first air interface and a second receiver (56) configured for the second air interface are synchronized to a common frequency and timing reference (84). 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.

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 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 includes, in a transceiver (28, 160), receiving from a repeater (32, 168) a received signal that includes a desired signal for reception and an undesired replica of a transmitted signal that was transmitted from the transceiver and retransmitted by the repeater. A local copy of the transmitted signal is generated in the transceiver. The local copy is matched with the undesired replica of the transmitted signal in the received signal, by adapting the received signal while retaining the local copy non-adaptive. An interference caused by the undesired replica to the desired signal is canceled, by subtracting the local copy from the adapted received signal.
