Description: Beyond third generation (B3G) and fourth
generation (4G) communication systems require
bandwidth efficiency and low complexity receivers to
accommodate high data rate and large number of
users per cell. This paper provides the
recommendations for why Interleave Division Multiple
Access (IDMA) stands out among all the present day
multiple access systems. Even if IDMA is a special
case of Code Division Multiple Access (CDMA), it
simply trounces CDMA as far as the cell capacity is
concerned. In IDMA, interleavers are used as the only
means for user separation. Interleaver size can be
varied for a set of users but the recommended
interleaver size is 1024bits at which it provides better
efficiency and minimum processing delay.
Investigations carried throughout this paper are while
using 1024 bit interleavers. IDMA exhibits the
tendency to handle huge number of users. Platform: |

Description: A Hybrid Orthogonal Frequency Division Multiplexing & Code-Division Multiple-Access (OFDM-CDMA)
This is a simulation program for uncoded OFDM-CDMA system with QPSK modulation
and Complex channel modelled by Rayleigh fading. The program is modified based
on Iterative chip-by-chip multi-user detection has been adopted in this simulation
