Multiple access design for impulse radio communication systems

We address the problem of designing time hopping codes for impulse radio multiple access communication systems. Time hopping techniques are first reviewed, including a new code that Iacobucci and Di Benedetto (see Proc. International Symposium 3G Infrastructure and Services, Athens, Greece,July 200) proposed for time hopping, and performance in terms of cyclic correlation properties are given. Advantages and disadvantages of different time hopping codes in terms of resource assignment for multiple access communication systems are analyzed and discussed.
