摘要： An adaptive weighted parallel interference cancellation system for CDMA that decreases MAI (multiple access interference) and thereby increases general performance, including K stages for iterative cancellation of MAI in a received signal of a user. Each stage includes a detector, a regenerator, and a subtractor. The detector is configured to determine a tentative bit decision from a despread signal. The regenerator that is connected with the detector in parallel is configured to spread an unmodulated signal, multiply a channel phase, and multiply by the output of the detector. The subtractor uses weighted signals that are adjusted user by user and according to changing environments.

摘要： Provided are an initial synchronization acquiring device and method in a parallel processed DS-CDMA UWB system and a DS-CDMA UWB system's receiver using the same. The initial synchronization acquiring device is constructed to include a correlator for correlating input signals and outputting correlation result values and an initial synchronizer for tuning initial symbol synchronization and frame synchronization by using the correlation result values received from the correlator and then storing combining mark values and a synchronization position value in a register, thereby making it possible to greatly decrease a system's complexity, compared to the existing method of separately designing respective modules for acquiring packet synchronization and symbol synchronization in the existing CDMA system. Also, the initial synchronization acquiring device and method additionally compensates a synchronization error caused by a frequency offset generated between clocks used by a transmitter and a receiver and thereby can be efficiently used in the high-speed and parallel-processed DS-CDMA UWB system.
