Description: OFDM信号具有高峰均功率比的特点，研究交织技术在抑制OFDM信号峰值平均功率比（PAPR）中的应用。论文首先阐述了OFDM的基本原理和关键技术，简单介绍了目前降低PAPR的几种方法，在对交织法降低OFDM系统的PAPR进行理论分析的基础上，提出了一套合理的交织方案――利用分组交织器和伪随机交织器降低PAPR，最后通过MATLAB仿真得出结论。-OFDM signal has a peak to average power ratio characteristic of interwoven OFDM technology in the inhibitory signal peak-average power ratio (PAPR) of the application. Thesis first expounded the basic principles of OFDM and key technologies, the simple introduction of the current of several methods to reduce PAPR, intertwined in the law to reduce PAPR of OFDM system, the theoretical analysis, based on a set of reasonable intertwined programs- use Packet interleaver and the pseudo-random interleaver to reduce PAPR, the final conclusion through MATLAB simulation.

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: In this coursework assignment, we implement an IEEE 802.11a based OFDM system and investigate the impact of different design parameters, e.g., modulation level, code rate, interleaver, equalizer, etc. on the system performance. The IEEE 802.11a system model to be implemented is shown in the lecture notes which can be found on SurreyLearn.-In this coursework assignment, implement an IEEE 802.11a based OFDM system and investigate the impact of different design parameters, eg, modulation level, code rate, interleaver, equalizer, etc. on the system performance.
