Latest Patents
One of Aldridge's latest patents is titled "High performance W-CDMA slot synchronisation for initial cell search with reduced hardware." This invention provides a method for slot synchronization during the initial cell search, utilizing two Finite Impulse Response (FIR) filters to correlate synchronization codes transmitted in the downlink. By taking a sign bit after the first FIR, the hardware requirements for the second FIR are significantly reduced. The correlated results can be processed using two different algorithms, which either add a square operation or take the magnitude before further processing. The results are accumulated and stored for each successive correlation, allowing the physical-layer processor to search for the peak position corresponding to the slot boundary.
Another significant patent is the "Method to adaptively scale the input to a channel decoder." This invention determines the range of effective bits within the output from an inner modem and selects the soft bits passed to a channel decoder. By using the average and standard deviation of values, the method avoids underflow or overflow that could degrade performance. The most significant bits from the effective range are passed to the channel decoder, enhancing its efficiency.
