    Abstract: A symbol combining device for multi-path diversity includes a plurality of demodulation circuits for demodulating received signals, a common memory for storing outputs of the demodulation circuits, a symbol combiner for receiving the outputs of the common memory corresponding to the demodulation circuits and for combining the outputs, and a memory controller for controlling the common memory to timely separate the write and read operations. To timely separate the write and read operations, the memory controller controls the common memory in order that the demodulation circuits sequentially access the common memory and the resultant outputs of the demodulation circuits are written in the common memory, and the symbol combiner reads the outputs of the demodulation circuits written in the common memory sequentially. Because the deskewer of the symbol combining device is constructed of a single memory, not FIFO by channels, the required number of gates is about 40% of the FIFO by channels, and the size of the symbol combining device is reduced to 40%. Further, the symbol combining device can be easily adaptable to change of the number of channels for various services.

    Abstract: A rake receiver for high data rate communications systems is provided that is able to share resources between demodulating branches without using independent hardware resources for each finger. The rake receiver of the present invention uses less circuitry while keeping functional equivalence, and it requires relatively smaller additional area when increasing the number of demodulating branches, thereby having a significantly smaller size, being able to track more demodulating paths for increasing performance, and being less complex as compared to conventional rake receivers for high data rate communications systems.

    Abstract: An apparatus and method for generating reference timings. Each of at least two Node Bs transmits a first channel signal for providing a reference timing and a second channel signal different from the first channel signal and a UE has a plurality of fingers for demodulating the first channel signals. A first timing generator receives an SFN of a reference Node B having a communication link established with the UE, selects a first channel FB timing from a reference finger, and generates an SFN reference timing based on the SFN and the selected first channel FB timing. A second timing generator generates a second channel FB timing to demodulate the second channel signal of the reference Node B from the selected first channel FB timing through offset control. A third timing generator generates an uplink channel FB timing having a predetermined offset from the second channel FB timing.
