Chirp spread spectrum (CSS) is a wideband modulation technique employing linear frequency sweep. We analyze the effects of frequency offset and timing jitter on the performance of CSS system. The exact bit error rate (BER) expressions of CSS system are derived in the presence of frequency offset and timing jitter. It is shown that analytical and experimental results match exactly and the frequency offset and the timing jitter degrade the CSS performance. In addition, we suggest tolerance criterion of the frequency offset and the timing jitter for reliable CSS based communication systems using simulation results.
