摘要：

An exact closed-form expression is developed for the probability density function (PDF) of the sum of independent but not necessarily identically distributed Nakagami-m random variables. By utilizing the newly developed PDF and the associated developments, new exact expressions of the bit error probability are presented for predetection equal gain combining diversity.
