Apparatus and method for coding/decoding TFCI bits in an asynchronous CDMA com munication system |
摘要 |
A method for decoding received data in a decoder which receives data from an encoder varying a length of a Walsh code according to a coding rate of transmission data, and has maximum IFHT (Inverse Fast Hadamard Transform) stages capable of decoding even the data encoded by a Walsh code with a maximum length. The method comprises selecting at least one IFHT stage among the maximum IFHT stages according to a length of the Walsh code used for the received data; and performing inverse fast Hadamard transform on the received data by the selected IFHT stage. <IMAGE> |
