SLM-3650 Satellite Modem
Options
Notes:
1. The occupied bandwidth is defined at the width of the transmitted spectrum taken
at the –10 dB points on the plot of power spectral density. This equates to 1.19 x
symbol rate for the SLM-3650 TX filtering.
2. Included for comparison purposes.
Observe that the 8=PSK Rate 3/4 Turbo performance closely approaches that of the Rate
2/3 TCM/Reed-Solomon case – the BER performance is within approximately 0.4 dB.
However, it should be noted that the Rate 3/4 Turbo mode is 20% more bandwidth
efficient than the TCM case. The additional advantages of Turbo (lower delay,
performance during fades, etc.) also should be considered.
