    摘要: Provided is a wireless relay system including multiple terminal station apparatuses and a base station apparatus. The base station apparatus includes: a base station reception unit that respectively receives pieces of upstream data traffic from the multiple terminal station apparatuses; an encoding unit that, if pieces of upstream data traffic that require mutual forwarding in opposite directions are present in the respective pieces of upstream data traffic, performs network encoding on the respective pieces of upstream data traffic such that the pieces of upstream data traffic are pieces of data traffic of mutually identical content; and a base station transmission unit that simultaneously transmits encoded data traffic as downstream data traffic to the multiple terminal station apparatuses. The terminal station apparatuses each include: a terminal station transmission unit that transmits the upstream data traffic to the base station apparatus; a terminal station reception unit that receives the encoded data traffic; and a decoding unit that decodes the encoded data traffic using the upstream data traffic.

    摘要: Systems and methods for correcting frequency error in a received signal include: receiving a satellite signal, the satellite signal having a bandwidth and a center frequency; determining the profile of the satellite signal; computing the center frequency of the satellite signal based on the profile of the received signal; and generating a reference signal at the computed center frequency. The systems and methods may further include computing a center frequency of each of a plurality of satellite signals based on the computed center frequency. Determining the profile may include sweeping a tuner above and below a given reference frequency; measuring the received signal strength during the sweeping operation; and determining the profile based on the received signal strength.

    摘要: A method and system for transmitting data is provided. The method includes receiving by a first interface device, data. The data is divided into a plurality of data packets and stored within an internal buffer. A first group of data packets are transmitted to a network node communicatively coupled to the first interface device. The first group of data packets are transmitted from the first communication device to a second interface device via a first communication network. A second group of data packets are transmitted to a first communication device communicatively coupled to the first interface device. The second group of data packets are transmitted from the first communication device to the second interface device via a second communication network associated with the first communication device.
