Modulation & Coding (Option 7) 1/2/2019 Modulation & Coding (Option 7) Bit-to- Symbol Symbol- to-Chip Symbol Repetition Pulse Generator Scrambling {0,1,-1} Ternary Sequence Bit to symbol mapping: group every 2 coded bits into a symbol (after ½ rate Conv Encoding) Symbol-to-chip mapping: Each 2-bit symbol is mapped to one of 4 32-chip sequence, according to 4-ary Ternary Orthogonal Keying Symbol Repetition: for data rate and range scalability Scrambling: with bipolar sequence @ 30.875MHz, to suppress cross correlation sidelobes due to excessive delay spread Pulse Genarator: Transmit Ternary pulses @ 30.875MHz Shahriar Emami (Freescale)

Conclusions Coherent: 1/2/2019 Conclusions Coherent: - Performance of Options I and 7 when demodulated by coherent receivers are roughly the same. - Option III (coherent) is about 4 dB inferior to options I and 7. Non-coherent: - Option 7 is 3 dB inferior to option I. Shahriar Emami (Freescale)
