Wireless-Based Application-Layer Cross-Layer Design ◾ 467
FEC code lies within the type of code used in the FEC scheme and the number
of bits. Another important factor in the performance of an FEC mechanism is the
types of encountering errors in the data transmission. e FEC codes suitable for
bursty data streams are different than those suitable for checking random single-
bit errors. Reference [58] presents a Reed–Solomon (RS) FEC coding system used
for bursty errors, which features an IEEE 802.11a wireless link. FEC techniques
are used to provide methods to reduce bit error rate (BER) figures on the wireless
link (i.e., IEEE 802.11a) using quadruple phase shift keying (QPSK) modulation
scheme, which offers a good tolerance to noise and interference. ...
