In this treatise we demonstrate, how a high spatial and frequency diversity can be achieved by combining differential space-time block coding (DSTBC) and fast frequency hopping (FFH). The proposed FFH assisted DSTBC scheme is capable of achieving a high diversity order given by the product of the frequency diversity order achieved by FFH and by the spatial diversity order offered by the DSTBC arrangement. Hence, the system is capable of exploiting the advantages of both DSTBC and FFH. Furthermore it is less vulnerable to some of their individual disadvantages, such as the performance degradation of DSTBC due to fast fading and the large bandwidth requirement of the FFH system. The proposed system also benefits from the employment of sphere packing and iterative turbo detection
