| Title: | Fundamental BER-floor for long-code CDMA | Authors: | Rasmussen, Lars K. Lim, Teng J. Sugimoto, Hiroki |
Issue Date: | 1998 | Citation: | Rasmussen, Lars K.,Lim, Teng J.,Sugimoto, Hiroki (1998). Fundamental BER-floor for long-code CDMA. IEEE International Symposium on Spread Spectrum Techniques & Applications 3 : 692-695. ScholarBank@NUS Repository. | Abstract: | In a discrete-time realization of a long-code CDMA system, a non-zero probability of encountering a singular channel (linear dependency among spreading codes) leads to an inherent error floor at high SNR. In this paper we derive a lower bound on this error floor for a synchronous CDMA system in AWGN. The lower bound is found to correspond closely to the error floor encountered by the full-complexity maximum-likelihood detector. | Source Title: | IEEE International Symposium on Spread Spectrum Techniques & Applications | URI: | http://scholarbank.nus.edu.sg/handle/10635/112334 |
