Comments on "An alternative derivation for the signal-to-noise ratio of a SSMA system"
D.V. Sarwate · IEEE Transactions on Communications · 1995
The "alternative derivation" proposed in the Letter referenced in the title (see ibid., vol.42, p.2224, 1994) is incorrect. The correct derivation gives a result that agrees with previous computations. Hence, the claims and conclusions based on the apparent difference in the results are not valid.
