摘要： Techniques for detecting acquisition of a false channel in a wireless communication system are described. For false channel detection, a peak corresponding to a signal from a base station is initially detected. Frequency acquisition and time tracking of the peak are then performed. The frequency acquisition attempts to determine and correct downconversion frequency error. The time tracking attempts to follow the peak as it moves due to sample timing error and/or changes in channel conditions. Whether the signal is from a desired frequency channel or a false frequency channel is determined based on the time tracking. If a false channel is acquired, then the sampling timing will be either too slow or too fast, and the peak will move at a fast rate. A false channel may be detected based on the movement of the peak.

摘要： In order to time track an incoming signal, a receiver demodulates a first instance of a signal to produce a first set of energy values corresponding to a set of possible data values of the signal. The receiver also demodulates a second instance of the signal to produce a second set of energy values corresponding to the set of possible data values. The receiver combines the first and the second sets of energy values to determine a combined set of energy values. The receiver determines a first estimate of a most likely transmitted data value based upon the combined set of energy values. The receiver decovers an early set of despread samples of the first instance using a symbol corresponding to the first estimate to produce a first early energy value. The receiver decovers a late set of despread samples of the first instance using the symbol corresponding to the first estimate to produce a first late energy value. Finally, the receiver determines a time offset of the first instance based upon the first early and the first late energy values.

摘要： The probability based lock detection circuit determines whether a signal is sufficiently strong for communications in a mobile telecommunications system. If a signal is below a maximum energy threshold, the probability based lock detection is used to determine if the receiver is sufficiently capable to detect the signal and combine the signal with other signals received to obtain data transmitted by a mobile telephone. The probability based lock detection involves comparing index representations of maximums of 64 possible energies sent by the mobile telephone that identify that the signal was sent by mobile telephone. A mobile telephone sends signal that arrives to a base station through multiple paths to ensure accurate data transmission. Each signal includes data that identifies the mobile telephone. The probability based lock detection circuit determines whether the index of the maximum of 64 possible values of a signal sent to identify the mobile telephone is the same as the index of the maximum of the 64 possible values as calculated by combining all of signals sent by the mobile telephone.

摘要： Techniques are provided to control the transmit power for data transmission on multiple transport channels having different signal quality (SIR) targets. A single SIR target is maintained for all transport channels, and this SIR target is adjusted based only on active transport channels. For each update interval, a data processor processes at least one data block received in the current update interval on at least one of the transport channels and provides the status of each received data block. A controller increases the SIR target based on an up step if any received data block is erased and decreases the SIR target based on a down step if all received data blocks are good. If any received data block is erased, the down step used to adjust the SIR target may be set to the smallest down step size required by all transport channels with erased data blocks.
