Abstract

Using a 4-node testbed at 253 Gchips/s, the capability of fast frequency-hopping time-spreading OCDMA to provide differentiated service by varying the code weight is demonstrated. Bit error rate variation of five orders is obtained. A proposed novel scheme enables variation of code weight, and hence service guarantees, on a per-bit basis.
