Equivalently, asymmetric signal constellation with Trellis coding outperforms conventional symmetric signaling in terms of BER in DS/SSMA systems [293].
In DS/SSMA systems, however, convolutional coding can be employed without bandwidth expansion by using shorter pseudonoise (PN) sequences. We will obtain the.
