A method of avoiding collisions among a plurality of transmitters that communicate asynchronously in relation to each other with a single receiver. The transmission scheme utilizes a randomization process to minimize the probability of collision among transmitted signals from different non synchronized transmitters, thus achieving improved overall link quality for each transmitter and improved system performance. The method has applications to many types of communications systems including frequency hopping spread spectrum communications systems. Transmitters send data in a burst of data packets, each sent during a time slot within the burst. Each time slot is divided into two or more sub time slots. During each time slot, one of the sub time slots is randomly chosen and the data packet is transmitted during that particular sub time slot. The larger the number of sub time slots used results in lower probability of complete transmission loss.
