Abstract：In spread spectrum system, frequency-domain interference suppression algo-rithms always use data windows to reduce the spectral leakage associated with truncation, and employ overlap to lessen the SNR degradation due to windowing. In this paper, the windowing degradation and the data composing are studied. An improved method has been put forward to compose the data after overlap based on Capozza’s(2000) method. The ana-lyzed and simulated results show that the new method leads to a less SNR degradation than Capozza’s method at the cost of a few more addition.
