Abstract
Spread spectrum communication systems are well known for their resistance to external interference. Adaptive excision of the interfering signal can increase this resistance. The design of an adaptive signal processing testbed for the real-time excision of interference is investigated. The testbed should be programmable for performance comparisons of different algorithms. Also, the use of the testbed for voice applications should be possible. The proposed design incorporates two TMS320C30 digital signal processor boards ina PC/AT host. Digital input is supplied from existing equipment. One board is used for the signal excision, while the other is used for the despreading/BER operations. The predicted maximum chip rate of this equipment does not meet the desired chip rate of 1 MHz. Experience used in designing this testbed will be used to select the optimum improvements to increase the data rate. TRUNCATED
