CDMA Reference Blockset

IS-95A Common Library

The Common Library provides the blocks that are used in the transmitter as well as the receiver, or in the forward as well as the reverse link.

Function	Block
Walsh code generation for forward channel orthogonal spreading and despreading, and reverse channel modulation	IS-95A Walsh Code Generator
Long code generation for forward link scrambling and power-bit insertion, and for reverse link spreading and data burst randomization	IS-95A Long Code Generator
Short code generation for spreading and despreading of both the forward and reverse link signals in quadrature	IS-95A Short Code Generator
CRC generation, which provides redundant bits for error detection	IS-95A CRC Generator
CRC syndrome computation for detecting errors in received data	IS-95A Syndrome Detector
Frame quality detection using a combination of CRC and Viterbi decoder metrics	IS-95A Frame Quality Detector
