摘要： There is provided a channel estimation apparatus for estimating a radio channel environment by multiplying a currently received bit signal of a pilot signal and previously received bit signals by weights, and summing the weighted currently received bit signal and the weighted previously received bit signals in a CDMA mobile communication system receiving the pilot signal comprised of a stream of bits having given bit values, and a power control signal comprised of power control bits. In the channel estimation, a predictor predicts a next bit signal succeeding the currently received bit signal, multiplies the predicted next bit signal by a weight, and generates a weighted next bit signal. A summer sums the weighted next bit signal from the predictor, the weighted currently received bit signal and the previously received bit signals.

摘要： An apparatus and method for receiving data when an HS-SCCH is not used in a mobile communication system are provided. In the apparatus and method, retransmission data is received, parameters including information about initial transmission data are acquired from the retransmission data, the initial transmission data is retrieved from a second-rate dematching input buffer based on the information about the initial transmission data, second-rate dematching is performed on the initial transmission data and the retransmission data, and first output data is generated by soft-combining the second rate-dematched initial transmission data with the second rate-dematched retransmission data. Accordingly, memory usage can be reduced.
