    摘要： In one embodiment, a cognitive radio system includes a first transmitter in communication with a first receiver via a wireless channel. The first transmitter receives a plurality of first packets, and transmits the first packets to the first receiver via the channel. A second transmitter in communication with a second receiver and the first receiver via the channel receives a plurality of second packets, receives the plurality of first packets from the first transmitter, and transmits the second packets to the second receiver via the channel. The second transmitter is configured to detect an idle state of the channel. Upon detecting the idle state of the channel, the second transmitter is configured selectively to transmit at least one of the second packets to the second receiver or to relay at least one of the first packets to the first receiver.

    摘要： Optimum usage of time diversity and significantly higher data rates are achieved by utilizing an adaptive Ultra-wideband impulse radio (UWB IR) transmission scheme based upon information about the channel state at a particular time instant. Through the use of channel state information (422), the transmission scheme (413) is adjusted for the particular channel state. In particular, the system is adapted dynamically for each user by varying the number of pulses (412) transmitted per bit in response to the channel state. The channel state is a dynamic parameter of the transmission system that is typically measured or estimated by the receiver (420). An adaptation element responds to the channel state information to determine a desired number of pulses per bit to be utilized in a transmission channel for subsequent UWB IR communication. This desired number of pulses per bit is then supplied to and used by an adaptive transmitter (410) for subsequent transmission by a particular mobile station.

    摘要： Signals transmitted on the backhaul links of a cloud radio access network may be compressed using joint compression encoding. Joint compression encoding may be performed using a successive estimation-compression architecture. Joint compression encoding may include designing preceding matrices that may be used with signal compression. Joint compression encoding may be applied to signals transmitted on the downlink of the cloud radio access network. One or more baseband signals to be delivered over the backhaul links may be jointly compressed using multivariate compression. Multivariate compression may be implemented using successive compression based on a sequence of minimum mean squared error (MMSE) estimations and per BS compression.
