Abstract: A method and apparatus processes a plurality of analog signals m a transceiver with multiple receive (Rx) antennas in a wireless communication system. By appropriate combining of the analog signals of each Rx antenna, this scheme allows a reduction in the number of the front end components, for example, filters, mixers and Analog to Digital Converter (ADC) devices Subsequently, the signals are separated digitally by virtue of their unique code. The benefits associated with this scheme are at least threefold. reduced cost, area, and power consumption of a multiple antenna terminal. Additionally, proper parameter settings increase signal to Quantization Noise Ratio (SQNR) at the ADC output.

Patent CA-2729035-A1 (CA)
Inventor: LARA OCHOA JOSE MANUEL FRANCISCO
IPC: C07C279/26
Filed: 2008-06-26
Abstract: In this invention, a new 1,1-dimethylbiguanide Glycinate salt was synthesised, called metformin Glycinate. This salt exhibits advantages over other metformin salts. These advantages are due, in the first place, to the fact that the glycine counterion exhibits hypoglycaemic effects by itself. Moreover, this salt exhibits more rapid absorption, reaching higher plasma concentrations than those produced with metformin hydrochloride. The synthesis was synthesised from the Metformin Hydrochloride salt, where free Metformin was produced by releasing the hydrochloride counterion, using an ion-exchange column for this purpose; the metformin base released was dissolved in an aqueous medium and, subsequently, glycine was added at ambient temperature under constant stirring; subsequently, the resulting product is heated until a concentrated solution is produced, an organic solvent is added which does not react with the components present and wherein glycine is insoluble in order to create insolubility in the medium and favour crystallisation of the saturated medium;  all this in order to precipitate the excess glycine and then separate it by filtering; the filtrate was concentrated again until precipitation of the metformin glycinate salt was achieved.
