    摘要: A method includes holding in a memory of a receiver, for each temperature in a range of temperatures, a respective first parameter indicative of a frequency error of a crystal oscillator in the receiver at the temperature, and a respective second parameter indicative of an uncertainty of the first parameter. An operating temperature of the crystal oscillator is measured. One or more frequencies, for initial acquisition of signals from a transmitter, are selected based on the first and second parameters corresponding to the measured operating temperature. The receiver is tuned to receive the signals from the transmitter on at least one of the selected frequencies.

    摘要: Briefly, a wireless communication device, a wireless communication system and a method of controlling a transmission power level of a dedicated channel signal transmitted in a compress mode with an alternate scrambling code. The method includes transmitting one or more power control commands to a base station to control a transmission power of one or more frames scrambled by primary scrambling codes and prior of receiving a dedicated channel signal scrambled by alternate scrambling codes, transmitting one or more pre-alternate scrambling codes power control commands.

    摘要: A communication system includes a lattice interfered channel to transmit data from a transmitter to a receiver. In one embodiment, an encoding-modulation scheme having a rich signal constellation is used to encode data at a total rate of 0.7 bit/dimension or less before transmission into the lattice interfered channel. In another embodiment, decoding metric approximation techniques are used to process signals received from the lattice interfered channel. In still another embodiment, multilevel code (MLC) decoding is used to jointly decode an error correction code component and a lattice/MLC component of a received signal. The error correction code component may then be extracted from the decoded signal.

    摘要: A method for communication includes defining a signal constellation including multiple constellation points in a signal space, such that each constellation point corresponds to a signal representing a respective combination of values of at least three bits, wherein three or more subsets of the bits in each of the constellation points are respectively allocated to three or more data streams. A sequence of signals is received, each signal selected from the signal constellation. The received sequence of the signals is demodulated, and one of the three or more data streams is reconstructed based on the demodulated signals.
