Performance of a Direct Sequence Spread-Spectrum System with Long Period and Short Period Code Sequences
R. Lunayach · IRE Transactions on Communications Systems · 1983
In this paper, the performance of a direct sequence spread-spectrum system is analyzed with both a long period sequence and with a sequence whose period is one bit long. Bit error rates for both quadriphase and biphase chip spreading, in conjunction with both QPSK and BPSK data, are considered in the presence of noise and jamming. The frequency location of the jammer is arbitrary.
