Abstract
The Galileo spacecraft employs concatenated coding schemes with Reed-Solomon interleaving depth 2. This article compares the bit error rate (BER) performance of Galileo’s concatenated codes, assuming different interleaving depths (including infinite interleaving depth). It is observed that Galileo’s depth 2 interleaving, when used with the experimental (15, 1/4) code, requires about 0.4 dB to 0.5 dB additional signal-to-noise ratio to achieve the same BER performance as the concatenated code with ideal interleaving. When used with the standard (7, 1/2) code, depth 2 interleaving requires about 0.2 dB more signal-to-noise ratio than ideal interleaving.
