Abstract
In this paper, we introduce and outline the concept of Channel Code Division Multiple Access (CCDMA) using a design example based on the recently proposed Multilevel Structured (MLS) LDPC codes. We succeeded in making the memory requirements of the multi-user transceiver to become practically independent of the total number of users supported by the system as well as ascertain that each user benefits from the same Quality of Service (QoS). Finally, we will demonstrate that despite their beneficial compact structure, the proposed MLS LDPC codes do not suffer from any Bit Error Ratio (BER) or Block Error Ratio (BLER) performance degradation, when compared to an otherwise identical benchmarker scheme using significantly more complex LDPC codes having pseudo-random parity-check matrices.
