Performs the DSSS spreading operation using the spreading code that you specify. The spreading code algorithm performs non-return-to-zero (NRZ) encoding of the input bit stream and the spreading code. However, the output is an array of zeros and ones.

## input bit stream

The sequence of information bits to be spread.

The sequence of bits that determine how the bits in input bit stream are spread.

## error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: no error

## output chip stream

The sequence of data bits that is spread for transmission. The number of elements returned in this array equals the product of the input bit stream array length and the spreading code array length.

## error out

Error information. The node produces this output according to standard error behavior.
