Abstract: A method for determining a Modulation and Coding Scheme (MCS) and power control includes determining an error rate of a communication channel between the UA and at least one of the base station and the RN. When the error rate is below a first threshold, the method includes at least one of increasing the MCS, and reducing a transmission power of the UA. When the error rate is above a second threshold, the method includes at least one of decreasing the MCS, and increasing a transmission power of the UA.

Abstract: A communication system receives a binary sequence from a sensor, identifies a power consuming characteristic of the binary sequence, and determines an error component configured to reduce the power consuming characteristic of the binary sequence. The system compares the error component to an error tolerance deviation, and if the error component is below the error tolerance deviation, combines the error component with the binary sequence to produce an output sequence and transmits the output sequence via a serial interface to a receiver configured to receive the output sequence. The error threshold is based in part on an error tolerance characteristic of the receiver.

Abstract: A system includes a packet generator, a preamble generator, and a modulator. The packet generator generates a packet including a preamble for transmission via a sub-1 GHz channel. The preamble generator generates the preamble for the packet. The preamble includes a first signal field and a second signal field. The first signal field and the second signal field conform to a Very High Throughput format specified in a wireless networking standard. The modulator modulates both the first signal field and the second signal field of the preamble using the same modulation scheme in response to the packet being a single user packet. The modulator modulates the first signal field and the second signal field of the preamble using different modulation schemes in response to the packet being a multiuser packet.

Abstract: The disclosure relates to a method for serially transmitting a frame from a transmitter to at least one receiver via a bus line, as well as a subscriber station for a bus system. According to said method, stuff bits for generating additional signal edges are inserted into the frame by the transmitter according to a predetermined rule, and the stuff bits are removed again by the receiver when evaluating a received frame, a CRC calculation logic of a CRC generator calculating a CRC checksum that is comprised by said frame, and a value of “1” being inserted into said CRC calculation logic in an additional evaluation step if a value of “0 . . . 0” has been determined for the CRC checksum in the running calculation executed by the CRC calculation logic.

Abstract: Systems and methods for subframe-based link adaptation for a radio signal in a cellular communications network are disclosed. In one embodiment, a base station obtains a hybrid automatic repeat request acknowledgement for data transmitted between the base station and a mobile terminal in a radio signal of the base station. The base station then updates a parameter (e.g., SINR offset) used to control a Modulation and Coding Scheme (MCS) for transmission of data between the base station and the mobile terminal in the radio signal for one or more subframes in a frame structure of the radio signal based on the hybrid automatic repeat request acknowledgement. The one or more subframes are a subset of all of the subframes in the frame structure of the radio signal.

Abstract: An audio signal transmission system includes a first device and a second device. The first device transmits audio signals to the second device for the second device to process the audio signals and recognize data in the audio signals. After converting a piece of information read by the first device into digital data, the first device performs data state conversion algorithm to generate a time-based byte sequence, modulates the byte sequence to a set of audio signals, and transmits the set of audio signals. When receiving the set of audio signals, the second device filters and demodulates the set of audio signals to acquire the byte sequence, and converts the byte sequence into readable information. As the byte sequence has time-based characteristics, multiple independent pulse signals can be constantly provided to enhance audio signal recognition and ensure accuracy and stability of the audio signal transmission system.

Abstract: Presented herein are downstream recovery (error correction) techniques for an aggregated/consolidated media stream. In one example, a consolidated media stream that includes source media packets from one or more sources is sent to one or more downstream receiving devices. Based on the source media packets, one or more self-describing recovery packets for downstream error correction of the source media packets are generated. The self-describing recovery packets include a mapping to the source media packets used to generate the self-describing recovery packets, thereby avoiding the addition of error correction information in the consolidated media stream. The one or more self-describing recovery packets are sent to each of the downstream receiving devices as a separate stream.
