چکیده

An attempt is being made to construct an FM broadcast receiver utilizing relatively few tubes but incorporating the principles of multipath interference reduction. The parts to be constructed are the i-f amplifier, a two-tube limiter, a discriminator and an audio amplifier stage. A bandwidth of 2 Mc for the limiter and discriminator was chosen after a study of multipath interference in cities showed this to be a reasonable compromise. A one-tube discriminator to handle this bandwidth at 10.7 Mc has been developed in place of the balanced tWo-tube arrangements previously used.

Indoor Non-directed Optical Wireless Communications - Optimization of the Lambertian Order

For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...

Optimization Capabilities of LMS and SMI Algorithm for Smart Antenna Systems (RESEARCH NOTE)

In the present paper convergence characteristics of Sample matrix Inversion (SMI) and Least Mean Square (LMS) adaptive beam-forming algorithms (ABFA) are compared for a Smart Antenna System (SAS) in a multipath environment. SAS are employed at base stations for radiating narrow beams at the desired mobile users. The ABFA are incorporated in the digital signal processors for adjusting the weight...

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
