摘要： A first unit for use in a base station in a mobile telecommunication network is adapted to use an identity for identifying a mobile terminal or for identifying a channel in the uplink. The first unit manages information of at least one additional identity of a mobile terminal or a channel belonging to at least a second base station for interference mitigation purposes. The first unit detects whether the mobile terminal or channel identified by the additional identity is active and mitigates cell-interference caused by an active mobile terminal or a channel identified by the additional identity. A second unit reserves at least one identity for identifying a mobile terminal or for identifying a channel in order to make the at least one identity identifiable to at least a second base station.

Each signal has been modulated according to a different modulation scheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.

摘要： A method includes receiving a signal in a frequency band, which is assignable at least to a communication protocol in which Cyclic Prefixes (CP) are added to symbols having a predefined symbol interval. Multiple autocorrelations of the received signal are computed with a fixed time offset that depends on the symbol interval defined in the communication protocol, and the multiple autocorrelations are accumulated to produce a cumulative autocorrelation. An identification is made, based on the cumulative autocorrelation, whether the received signal is formatted in accordance with the communication protocol.

摘要： A system and method that scrambles the phase characteristic of a carrier signal are described. The scrambling of the phase characteristic of each carrier signal includes associating a value with each carrier signal and computing a phase shift for each carrier signal based on the value associated with that carrier signal. The value is determined independently of any input bit value carried by that carrier signal. The phase shift computed for each carrier signal is combined with the phase characteristic of that carrier signal so as to substantially scramble the phase characteristic of the carrier signals. Bits of an input signal are modulated onto the carrier signals having the substantially scrambled phase characteristic to produce a transmission signal with a reduced PAR.

摘要： This invention discloses a method for communications faster than the Nyquist rate (FTN) and faster than the Shannon rate which method is Quadrature Layered Modulation (QLM). QLM properties include scaling the data symbol pulses to maintain the same error rate performance for all rates. QLM alternatively considers the increase in the data symbol rate to be a layering of additional communications over the same link. The Shannon bound is a limit on the capacity of a communication link when transmitting data symbols at the Nyquist rate. QLM observes one can communicate at FTN to transmit more information than the Shannon rate since the Nyquist rate captures the information in a frequency band and does not constraint the information. These properties describe QLM and a separate math proof-of-concept is disclosed. Implementation and performance data demonstrate QLM can support communications data rates which are at least double the Shannon rate.
