Multicarrier modulation techniques like
orthogonal frequency division multiplexing (OFDM) and frequency division
multiplexing (FDM) have recently been introduced as robust techniques against
intersymbol interference (ISI) and noise, compared to single carrier
communication systems over fast fading multipath communication channels.
Therefore, multicarrier modulation techniques have been considered as a
candidate for new generation, high data rate broadband wireless communication
systems and have been adopted as the related standards. Several examples are
the European digital audio broadcasting (DAB) and digital video broadcasting
(DVB), the IEEE standands for wireless local area networks (WLAN), 802.11a, and
wireless metropolitan area networks (WMAN), 802.16a. In this study, low density
parity-check (LDPC) codes, space-time block codes (STBC) and convolutional
codes, which are known as error control codes, are discussed in multi-input
multiple-output orthogonal frequency division multiplexed (MIMO-OFDM) systems.
First, the structure of space-time block codes is explained. Then space-time
block codes are compared with low density parity check codes and convolutional
codes. Specifically, performance results for additive white Gaussian noise
(AWGN) channel in binary phase shift keyying (BPSK) systems of these three
codes have been compared. Bit error rates (BER) on binary phase shift keyying
systems of space-time block codes, low density parity check codes and
convolutional codes are simulated using matlab. Simulation results show that
space-time block codes provide better performance than the other two error
control codes.

Dikgen frekans bölmeli çoğullama (OFDM)
ve frekans bölmeli çoğullama (FDM) gibi çok taşıyıcılı modülasyon
tekniklerinin, hızlı değişen çok yollu iletişim kanallarında, semboller arası
girişimlere (ISI) ve gürültülere karşı tek taşıyıcılı iletişim sistemlerine
göre çok daha dayanıklı olduğu yapılan olduğu son yıllarda ortaya konmuştur. Bu
nedenle yeni nesil data hızı yüksek, geniş bandlı kablosuz iletişim sistemleri
için, çok taşıyıcılı modülasyon teknikleri aday olarak düşünülmekte ve standart
olarak yerleşmektedir. Örnek olarak Avrupa sayısal radyo yayın sistemi (DAB),
sayısal televizyon sistemi (DVB), kablosuz yerel bilgisayar ağları standardı
(IEEE 802.11a) ve kablosuz metropolitan bilgisayar ağları (IEEE 802.16a)
verilebilir. Bu çalışmada, çok girişli çok çıkışlı dikgen frekans bölmeli
çoğullamalı (MIMO-OFDM) sistemlerde, hata kontrol kodları olarak bilinen düşük
yoğunluklu eşlik kontrol (LDPC) kodları, uzay-zaman blok kodları (STBC) ve
konvolüsyon kodları ele alınmıştır. Her üç kod için de ikili faz kaydırmalı
anahtarlama (BPSK) sistemlerinde, toplamsal beyaz Gauss gürültülü (AWGN) kanal
için performans analizleri yapılmış ve sonuçları karşılaştırılmıştır. Düşük
yoğunluklu eşlik kontrol kodları, uzay-zaman blok kodları ve konvolüsyon
kodlarının ikili faz kaydırmalı anahtarlama sistemleri üzerindeki bit hata
oranı (BER) karşılaştırması matlab programıyla simüle edilerek verilmiştir.
Simülasyon sonuçlarında, uzay-zaman blok kodlarının, düşük yoğunluklu eşlik
kontrol kodları ve konvolüsyon kodlarına göre daha üstün bir performans
sağladığı gözlemlenmiştir.
