    摘要: Methods, systems and devices for interference cancellation of high-power input signals in the analog domain are described. An example method of interference cancellation includes receiving, via an antenna, an analog signal comprising a signal of interest and one or more interfering signals, wherein the one or more interfering signals comprises a high-power interfering signal with a signal power greater than 15 dBm, determining, based on a reference signal corresponding to the high-power interfering signal, an update to at least one parameter of the reference signal, wherein the update is determined by minimizing a cost function of a difference between the reference signal and the high-power interfering signal, generating, based on the update to the at least one parameter, a modified reference signal, and generating, based on coupling the modified reference signal to the analog signal, an interference-canceled signal comprising the signal of interest.

    摘要: Devices, systems and methods for high-utilization low-latency multi-channel time-division multiplexing access (TDMA) are described. One example method for wireless communication includes performing, in a first time interval of a time-division multiple access (TDMA) slot, a transmission of a first data unit over a first logical channel of the plurality of logical channels, refraining from transmitting, subsequent to a completion of the transmission of the first data unit, for a second time interval immediately after the first time interval, and performing (N-1) transmissions in (N-1) time intervals for each data unit of (N-1) subsequent data units in the TDMA slot, such that a transmission of an nth data unit of the (N-1) subsequent data units is performed over an nth logical channel of the plurality of logical channels.

    摘要: A method and system for maximizing throughput and minimizing latency in a communication system that supports heterogeneous links is presented. The communication system supports a primary link and an alternate link, and the method and system leverage the alternate link to reduce the overhead transmitted over the primary link, thereby increasing throughput and reducing end-to-end latency. The higher latency alternate link provides a delayed version of an information signal that corresponds to a portion of the information signal that is transmitted on the primary link. The received samples from the primary and alternate links may be used to equalize subsequent portions of the information signal received over the primary link, and may also be used for synchronization, timing recovery, DC offset removal, I/Q imbalance compensation, and frequency-offset estimation.

    摘要: A method and system for flexible radio communications using a wideband radio includes a wideband radio and multiple separable radio definition modules, wherein the wideband radio is configured to operate over a large portion of the radio-frequency (RF) spectrum and each of the radio definition modules are configured to operate in a specific frequency band. The separability of the radio definition modules maintains the capability of the wideband radio to operate over the large portion of the RF spectrum, as well as enabling its robust and reliable operation in a specific frequency band associated with the attached radio definition module.

    摘要: Systems and methods are presented for controlling the peak-to-average-power of a baseband orthogonal-frequency-domain multiplexing (OFDM) signal by designating a subset of the available subcarriers as information-bearing data-subcarriers, and loading remaining subcarriers by symbols that are a function of the symbols loading the data-subcarriers. At the receiver, the data-dependent subcarriers are optionally combined with data-subcarriers to increase error protection.

    摘要: Embodiments of the present invention provide Forward Error Correcting Code encoders and decoder structures that use DRAM in their memory designs. DRAM is a very attractive memory options in many electronic systems due to the high memory density provided by DRAM. However, the DRAM is typically not included in ASIC or FPGA implementations of encoders and decoders due to complex refresh requirements of DRAM that are required to maintain data stored in DRAM and may interfere with user access to the memory space during refresh cycles. Embodiments of the present invention provide FECC encoder and decoder structures that are implemented using DRAM that do not require complex refresh operations to be performed on the DRAM to ensure data integrity. Accordingly, embodiments of the present invention maximize memory density without the added complexity of introduced by the refresh requirements of DRAM.
