Secondly, for this canonical channel, we pro-pose new multilevel codes based on partitioning a signal con-stellation carved out from the integer latticeZn.

In mobile communications systems, there has been a grow-ing demand for high data rate services such as video phone,high-qualit y digital distribution of music, and digital televi-sion terrestrial broadcasting (DTTB) [1]. In such systems,the delay spread of the channel becomes a major i[r]

5. CONCLUSIONSIn this paper, we derived a union bound for coded FHSSsystems with MAI. Results show that the performance lossdue to interference increases as the hop length increases (orin other words as the number of hops in FHSS systemsdecreases). This performance loss increases as the number ofuse[r]

We further observe that the pro-posed FSOK MC-CDMA system exhibits a lowerPAPR than the conventional WH MC-CDMA andlocalized SC-FDMA systems.
