This paper proposes a new multicode interference cancellation algorithm which uses frequency responses of the channelization codes used in HSDPA system. The proposed algorithm estimates the multicode interference components at the chip rate, and then it improves the detection performance e by removing the estimated interferences from received signal.

This paper details the implementation of an agent-based educational gaming environment utilizing the REAL cognitive framework (Reflective Agent Learning Environment). REAL provides an interactive learning environment that allows students to 1) construct their imaginary world; 2) reflect upon the quality of their understanding; 3) test it out in the(More)
The HARQ enables the error correction of the unsuccessfully decoded transport block, but it requires redundancy retransmissions and delay in receiving an acknowledgement. In order to provide the flexibility of scheduling, the DL of LTE system uses the asynchronous HARQ so that retransmissions occur at any time. Generally in the FDD, the HARQ round trip time(More)
