A method and apparatus having a modified Reed-Solomon decoder is used for finding a specific code group used by a base station and the frame timing synchronization with the base station. The modified Reed-Solomon decoder uses a standard Reed-Solomon decoder and some reliability measurements computed from the received code word symbols. If the reliability of a received symbol is too low, this symbol is considered as erasure. By selecting code word symbols with higher reliabilities and erasing code word symbols with lower reliabilities, the symbol error probability is reduced and the performance is improved. Several modified Reed-Solomon decoders and a few decoding strategies are introduced in order to decode the received code word sequences with a power- and memory-effective method.

A nonlinear conversion system using precision mapping and the method thereof are described. The system includes a source value converter, a mapping table unit, a recovering parameter computing unit, and an output computing unit. The method includes the steps of: receiving an input value; converting the input value into a source value; mapping the source value to a destination value in a limited domain for restricting the calculation within a destination domain; establishing a mapping table by directly selecting a precision according to the destination domain and inverse-mapping back to a source domain; and outputting the destination value according to the mapping table, combining the destination value with a recovering parameter for recovering an output value produced by the nonlinear conversion of the input value.
