The performance of direct-sequence spreadspectrum (DS-SS) in packet radio networks suffers from the near-far problem. This near-far problem can be alleviated by using either a multiuser receiver or a single-user adaptive receiver along with centralized or distributed power control. This paper compares the feasibility of using a multiuser receiver based on the selective parallel or successive in...

Any radio system can be disrupted by interference. The end user naturally expects a reasonable degree of interference immunity in the design. In many cases, though, there is no definition of what is reasonable and no agreement on test methods. The interference performance of radio equipment sold to non expert customers can range from downright negligent to surprisingly good. This paper reports ...

This master thesis describes a radio receiver with simple architecture which operates at 20 MHz. This is based on low-cost amplifier design. Super-regenerative receiver (SRR) is re-examined for its simplicity, low-power, and short-range wireless applications. Power consumption is kept to a minimal level without any change in the performance of receiver by providing minimum biasing to discrete d...
