The performance of multi-pulse pulse position modulation (MPPM) using an avalanche photodiode (APD) is evaluated in optical intersatellite links (ISL's). We derive theoretical expression of bit error rate (BER) of MPPM with output statistics of APD which employ Gaussian distribution. We evaluate BER performance under the conditions that bit rate is constant (200 Mbits/s) and that bandwidth is limited (slot time period is 2.5 ns). The performance of (7,2) MPPM and (9,2) MPPM are compared with that of 4-ary PPM under both conditions. It is shown that (9,2) MPPM using the APD has better BER performance than 4-ary PPM using the APD in optical ISL's on both conditions when average photons/nat is somewhat large.
