Abstract: A method and system thereof for determining feedback for iterative channel estimation based on the summation of soft output decisions or Bit Error Rate (BER) derived from the output of an equalizer. The channel impulse response initially obtained according to a training sequence is used to estimate the received signal, and output hard values. The BER of the training sequence is calculated and judged, and if the BER is too high, the channel is estimated again according to the feedback until the BER satisfies a predetermined value. If the BER is still unsatisfactory after a predetermined number of trials, the channel is assumed to be an authentic bad channel, thus terminating the feedback procedure. If the equalizer is capable of outputting soft output decision, the summation of soft outputs is used instead of BER to determine whether feedback is appropriate.

Abstract: A path metric computation method and apparatus for estimating a maximum likelihood sequence in a wireless communication network. The proposed method applies the statistical properties of estimated channel impulse response to reduce the computational load. A threshold is set to check the significance of each autocorrelation value in order to determine the contribution to the path metric increment. The corresponding terms in the path metric equation with insignificant autocorrelation values are thus discarded to reduce the complexity of path metric computation.

Abstract: This present invention is a system and method to adjust a searcher threshold parameter of a RAKE receiver. The adjusting system includes a searcher, a power estimator, and a parameter control apparatus. When the searcher finds and acquires a new path signal, the power estimator will estimate the power of the new path signal and that of the other path signals. The parameter control apparatus will calculate and monitor the power ratio corresponding to the new path signal. If the power ratio remains smaller than a predetermined power ratio parameter for a first predetermined times, the parameter control apparatus will increase the value of the threshold parameter. If the power ratio remains unchanged for a second predetermined times, the parameter control apparatus will lower the value of the threshold parameter. After that, the searcher will acquire the path signals among the multipath signal being searched in accordance with the adjusted threshold parameter.

Abstract: Within a synchronization stage, m candidates are selected according to secondary correlation results that are generated in a standard code group and slot number identification process. Each candidate contains a respective code group number and slot number, and m is greater than 1. A primary scrambling code correlation process is performed with each candidate to obtain a corresponding primary correlation result for an associated primary scrambling code number. The primary scrambling code correlation process for each candidate is performed over x slots, where x is determined by the ratio f/m, f being the number of slots per frame, and x being less than f. Within integer constraints, x is ideally f/m. The respective code group number, slot number and primary scrambling code number of the candidate having the greatest primary correlation result are then selected as a synchronization result.

Abstract: A method for performing frame synchronization in a WCDMA system includes first, correlating a received signal with a plurality of predetermined correlators to obtain a plurality of frame synchronization correlation results, then, coherently combining frame synchronization correlation results with a slot synchronization phase when a test phase difference is less than a threshold phase difference, or, coherently combining frame synchronization correlation results with a linear combination of slot synchronization phases when the test phase difference is greater than or equal to the threshold phase difference. The slot synchronization phase is determined by correlating the received signal with a slot synchronization sequence. Lastly, the method determines a frame boundary of the received signal based on the coherent combination results. The method accommodates for a changing signal to noise ratio to improve frame synchronization speed and accuracy.

Abstract: The present invention provides a method and apparatus for determining the data transmit diversity mode of a base station. The present invention first estimates a first feedback weight of the mobile unit during a first slot. The first feedback weight has a first phase. Then, the present invention estimates a second feedback weight of the mobile unit during a second slot. The feedback weight has a second phase. A phase difference is obtained by comparing the first phase with the second phase. The present invention determines the applicability of closed loop transmit diversity mode according to the phase difference. Besides, if the feedback error rate is too high, the present invention commands the base station to tune off the closed loop transmit diversity for better performance.

Next is to generate a soft data by means of an equalizer according to the CIR of the training sequence. Subsequently is to estimate CIRs of data sequences according to the interposed training sequence by correlation channel estimation. Next is to define a weight by means of auto-correlation of the estimated data sequence and then to cancel the interference of channel by the weight. Finally is to use the soft data and the non-interference CIR to find out the data stored in the data sequence.
