| description | Due to the rapid growth in wireless communication systems, Long Term Evolution
(LTE), mainly based on Orthogonal Frequency Division Multiplexing (OFDM), no
longer meets wireless communication systems request and higher data rate
requirements. Thus, to support a number of users, higher throughput, reliability, and
lower latency, 5G is a candidate to meet these features. Furthermore, OFDM does not
meet the demand of 5G because of its high Out Of Band Emission (OOBE) and Peak
to Average Power Ratio (PAPR). Filtered-OFDM (f-OFDM) is considered an
alternative waveform for OFDM and a candidate technique for 5G because of its lower
OOBE and similar features of familiar OFDM. However, there is a trade-off among
reducing OOBE, Bit Error Rate (BER) degradation, and rising PAPR. Therefore, a
novel BCS code has been proposed in this thesis for the filtered-OFDM system to
improve BER performance with maintaining its low OOBE. It is created using a new
methodology that differs from conventional concatenated RS/BCH codes. Hence, an
inner RS (7, 1) code has been proposed to achieve compatibility with an outer BCH
(15, 5) code and appended by interleaver to create a novel BCS code with low
complexity. The results showed that using a novel BCS code in LTE system reduces
BER, significantly improved to be better than single and concatenated RS/BCH codes
with low decoding complexity. On the other hand, using a novel BCS code in f-OFDM
system achieved 0.8dB coding gain at 8×10-3 BER and 1dB coding gain at 2×10-3
BER versus conventional OFDM system in both BPSK and QPSK modulation
schemes, respectively. Meanwhile, the proposed system reduced both OOBE and
PAPR lower than the conventional OFDM system. In conclusion, due to its low
OOBE, improving BER, and minimizing PAPR better than conventional OFDM
system, the proposed system is presented as a high competitor candidate of 5G wireless
communication systems. |
