摘要： A digital baseband (DBB) receiver for receiving and processing a wireless communication signal. The DBB receiver includes at least one low noise amplifier (LNA), at least one demodulator, a direct current (DC) discharge circuit and an LNA control circuit. The LNA selectively amplifies the communication signal. The demodulator outputs analog real and imaginary signal components on real and imaginary signal paths, respectively, in response to receiving the communication signal from the LNA. The DC discharge circuit selectively discharges DC accumulating on at least one of the real and imaginary signal paths. The LNA control circuit turns the LNA on or off.

摘要： A base station for controlling transmission power during the establishment of a communication channel utilizes the reception of a short code during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional access code. The ramp-up starts from a power level that is lower than the required power level for detection by the base station. The power of the short code is quickly increased until the signal is detected by the base station. Once the base station detects the short code, it transmits an indication that the short code has been detected.

摘要： A base station for carrier offset recovery. An adaptive matched filter produces a filtered signal. A rake receiver provides relative path values of multipath components. A mixer generates channel impulse response estimates. A channel despreader despreads the filtered signal using the pseudo-noise signal generated to produce a despread channel signal of the selected channel. A pilot channel despreader despreads the filtered signal using a pseudo-noise signal generator to produce a despread pilot signal of the pilot channel. A hard decision processor determines a symbol value of the despread channel signal. A complex conjugate processor generates a complex conjugate of the symbol value as a correction signal. A phase-locked loop produces a phase correction signal to recover carrier offset.

摘要： A method and apparatus for providing a wireless transmit/receive unit (WTRU) with access to at least one peripheral device, and/or at least one peripheral device associated with an available auxiliary device. The current peripheral device requirements of the WTRU are determined. The radio frequency (RF) environment of the WTRU is scanned to determine if there are any available wireless peripheral devices or wireless auxiliary devices proximate to the WTRU. A determination is also made as to whether there is a wired peripheral device or a wired auxiliary device available. A list of currently available peripheral devices is compiled by scanning at least one peripheral device registry associated with at least one of a wireless auxiliary device and a wired auxiliary device. The list is presented on the WTRU's display and a user selects at least one of the available peripheral devices from the list.

摘要： A transmitter splits a user-data stream into a plurality of sub-streams. The transmitter then adaptively selects a modulation scheme and coding rate for each of the sub-streams based on current channel conditions. Next, a plurality of sub-carriers are modulated and encoded with the sub-stream data according to the selected modulation schemes and coding rates. The modulated sub-carriers are each allocated to one or more transmit antennas for transmission. Prior to transmission, a transmission power for each of the sub-carriers is adjusted based on the channel conditions. The adaptive modulation and coding function, the sub-carrier allocation function, and the power control function are jointly controlled to optimize throughput, signal quality, and system efficiency.

摘要： At a first communication station, communications from a second communication station are received. The first station transmits power commands based on in part a reception quality of the received communications. From the first communication station, a first communication having a transmission power level in a first time slot is transmitted. At the second communication station, the first communication and the power commands are received. A power level of the first communication as received is measured. A pathloss estimate is determined based on in part the measured received first communication power level and the first communication transmission power level. A transmission power level is set for a second communication in a second time slot from the second station to the first station based on in part the pathloss estimate weighted by a quality factor and the power commands.

摘要： A system for automatic gain control prevents input overload by precisely controlling the input level of a received, digitally modulated signal without using a variable gain amplifier. A limiting amplifier in conjunction with a logarithmic detector splits an input signal path in two, providing separate phase and amplitude information for downstream digital signal processing, where the separate phase and amplitude information is processed without variable gain artifacts. The separated phase information may further be divided into I and Q signals.

摘要： A method for facilitating inter-system handover by a multi-mode wireless transmit/receive unit (WTRU) is disclosed. The WTRU is capable of communicating in multiple wireless communication systems using different wireless communication protocols. A first wireless communication system provides a hot spot within the coverage area of a second wireless communication system. A base station in a cell in the second wireless communication system generates and transmits a message to inform the WTRU of the existence of the hot spot located in the vicinity of the cell. The WTRU receives the message and is therefore informed of the existence of the hot spot in the vicinity of the cell.
