Proposed MC code for GPS: (a) The entire 2.048 MHz band is uniformly divided into 1024 subcarrier slots, where the first and last 8 are left blank while the remaining 1008 are divided into 42 groups, each with 24 subcarriers. (b) 42 subcarriers are allocated to the k^th SV, k = 1, 2, ..., 24, which is made up of the k th subcarrier slot in each group.
