Title: Radio Communication System has Centralised Channel Coding/Decoding
Inventor: BENN HOWARD
IPC: H04W88/08
Filed: 1995-12-05
Abstract: Signal processing for multiple Radio Frequency (RF) heads (162-172) of a communication system (160) is located at a central control unit (158), such as a base station transceiver. More particularly, in the case where the RF head requires transmission and reception capabilities (in a TDM pico-cellular environment, for example), the central control unit is arranged to undertake power intensive channel coding and channel decoding for each of the RF heads, while the RF heads principally contain RF circuitry required for communication. As such, power consumption and heat generation arising from signal processing is restricted to the central control unit (158), thereby allowing a reduction in the cost and physical size of the RF heads (162-172).

Title: Method for detecting nucleic acids
Inventor: HARBRON STUART
IPC: C12Q1/6844
Filed: 1997-04-14
Abstract: Hybrids formed between a target nucleic acid and a nucleic acid probe are detected by first treating the mixture with an enzyme reagent which substantially hydrolyses any single-stranded nucleic acid present and which is largely without effect on the hybrid, capturing the hybrid by means of an antibody reagent to form a complex, and detecting the complex so formed. The nucleic acid probe may itself be labelled with the enzyme reagent, and the hydrolysis step achieved simply be adjusting the pH of the reaction mixture. The approach may be applied to the detection of multiple target nucleic acids.
