Abstract: The present invention is directed to an improved telecommunication receiver for receiving wireless multi-path communication signals. A novel RAKE receiver and a time diverse integration system for the calculation of the relative power of received signal samples are provided. Preferably, the receiver is embodied in a UE or base station of a CDMA wireless telecommunication system, such as a 3GPP system.

Abstract: A method and apparatus for efficiently transmitting channel quality information on a radio channel in a mobile communication system are provided. The reporting cycle of channel quality information is changed adaptively according to time-varying characteristics associated with the Doppler frequency of a radio channel or the variation of the channel quality information. Therefore, the channel quality information is efficiently transmitted. Also, the decrease of unnecessary frequent information transmissions reduces an uplink interference power level and power consumption in user equipment (UE), as well.

Abstract: An apparatus and method for improving the performance of an error correction code against the effects of error waves in a Multi-Input Multi-Output (MIMO) communication system are provided. In a receiver of the MIMO communication system, a Minimum Mean Square Error (MMSE) receiver unit estimates transmitted signals from at least two paths using signals received at each of receive antennas, a signal deprocessor selects one of the estimated signals, stores the other estimated signal, assigns weighting values to the selected signal and a previous detected signal, combines the weighted signals, and detects transmitted data from the combined signal, a signal reproducer reproduces a transmitted signal from the detected transmitted data, and a subtractor updates the received signals by subtracting the reproduced transmitted signal from the received signals and provides them to the MMSE receiver unit.

Abstract: A system and method of wireless communication determines received signal timing deviation which is used to generate a timing advance for adjusting wireless transmit receive unit (WTRU) transmissions. An adaptive threshold for measuring the timing deviation is set based on the energy level of received WTRU signals. WTRU signal samples which exceed the threshold are evaluated to determine timing deviation.

Abstract: An apparatus and method for detecting the reception timing of a received signal in a mobile communication system are provided. Two time points having the same energy, earlier and later than the received signal, are detected. The energy ratio between other time points spaced from the two time points by the same interval is calculated and it is determined whether the energy ratio falls into a predetermined rage. If the energy ratio is within the range, the received signal is considered to have no effects from an interference signal or a neighboring signal.

Abstract: A system and method of wireless communication determines received signal timing deviation which is used to generate a timing advance for adjusting User Equipment (UE) transmissions. An adaptive threshold for measuring the timing deviation is set based on the energy level of received UE signals. UE signal samples which exceed the threshold are evaluated to determine timing deviation.

Abstract: The present invention is a receiver which includes a blind code detection device for determining the identity of a plurality of channels over which information is to be transmitted when the identity of all channels is not known by the receiver. The blind code detection device generates a candidate channel list filled with the identify of selected channels out of the plurality of channels. A multi-user detection device, responsive to the blind code detection device, processes those channels in the candidate code list.
