A Two-Power-Level Method for Multiple Access Frequency-Hopped Spread-Spectrum Communication
John J. Metzner · IEEE Transactions on Communications · 1984
This paper suggests a technique applicable to chip-synchronous frequency-hopping MFSK multiaccess communication whereby each user has some high-power-level slots and some low-power-level slots. The optimum proportion of high-power slots is slightly less than1/ewhereeis the natural logarithm base. For this optimum proportion, the data rate efficiency is improved by about 50 percent for fixed bit error rate in the interference-only case.
