Abstract :
This paper is concerned with the Improving Space Time Diversity In a Fixed Point-to-Point link Using LMS Based Interference Cancellers, carrying SDH signals with 30 MHz channel spacing. A system model is presented based on a proposal to achieve higher spectral efficiency and data rates. Signals are modulated with 8 QAM & with 64 schemes, and Reed Solomon codes are used for error control coding. The paper discusses these effects on transmission and presents methods to counter them. Specially, cross-polar interference are investigated in detail. The performance of the system is observed through simulation results and is compared with analytical results presented in different text and publications.
