... same time domain code is low. However, when the number of users using the same time domain code increases, intercode interference increases. In order to reduce the intercode interference, users are ... algorithm, determines the time domain and frequency domain spreading factors so that the frequency domain spreading is maximized while keeping the intrauser multicode interference on time domain codes low. Appendix Proof ... reduces intrauser mul- ticode interference, whereas increasing frequency domain spreading increases frequency diversity. Thus a trade-off between reduction of multicode interference and increased frequency...
