Abstract
This thesis revolves around the concept of orthogonality and how to manipulate the relation between carriers in order to find a new trend of multiple access techniques that could fulfil the exponential demand on data.
Orthogonality in general is a relation between two objects where each of them has no component of the other one within a space defined by a mathematical operation.
The well-known example is in geometry where two line are orthogonal in the same plan if they have a right angle relation in that plan, where the projection of one onto the other is zero. This is applicable in the three dimension spaces, vector spaces with different vector lengths, using dot product operation and also in frequency space using definite integration in detection phase.
The later type is what this thesis is concerned about, as this property holds for OFDM modulation. Among this thesis, we are investigating this property, the we proceed with the effect of drifting the system from its orthogonal points.
The subtlest subject is how to induce the theoretical model over a practical one to provide readiness for implementation in next generation mobile communication.
The target is enhancing the physical layer of the most recent standard of telecommunication by the time this thesis was carried out, namely LTE-Advanced.
LTE-A is an improved model of LTE, which was standardized short time after LTE, it was inevitable for that system to provide backward compatibility with LTE so as not to be obsolete.
The provided system model in this thesis also takes into the account the compatibility property which adds more agility to the system and increases the chances to be considered in next generation of mobile communication.
