A novel communication system named "OR cooperative UWB" is proposed by bringing OR (Opportunistic Relaying) to UWB system. Particularly, the exact and closed-form symbol error rate (SER) expression is derived firstly in this paper. In order to maximize the capacity considering fairness between users, a definition of equivalent mean channel gain is given, and a joint resource allocation algorithm is also proposed which includes three steps: sub-band allocation algorithm, relaying allocation algorithm and power allocation algorithm. Employing the conception of "relative requirement degree", the algorithm shows a distributed solution targeting relay partner selecting and increasing capacity while satisfying the users' QoS (Quality of Service) requirement. Simulations results validate the performance of the proposed algorithm.
