These two technologies are of the most developing ones in modern mobile communications and for the past few years, they have been competing in order to dominate the mobile world. The main two issues that are usually the determining points of which modulation techniques are to be used include the complexity and performance of such systems. A system that has a better performance and has a lower complexity is usually preferred over

Unformatted text preview: one that is lower performing and may be more complex to implement and use. OFDM has been used by operators in order to handle larger amounts of bandwidth that CDMA cannot accommodate for, whereas CDMA has been proven to be sufficient and more cost-effective for certain operators voice and broadband requirements. It is commonly believed that OFDM is a better performing system than CDMA since it achieves better Bit Error Rate (BER) and less fading effects than CDMA. Also, OFDM has also been known to be a less complex system than CDMA, yet CDMA is still being used in todays modern mobile communications systems. This paper will present a comparison between OFDM and CDMA in terms of performance and complexity....
