Receiver and method of receiving for an FDMA/TDMA radio system
First Claim
1. A receiver comprising:
- means for receiving a first plurality of signals at different frequencies at the same time;
means for generating a second plurality of signals, a mixer for receiving at the same time, the first plurality of signals at different frequencies and one of the second plurality of signals at a time wherein the second plurality of signals are received by the mixer in succession, said first plurality of signals being mixed with successive ones of the second plurality of signals; and
filter means for receiving signals output from said mixer, said filter means being arranged to provide a series of samples of the first plurality of signals at the same frequency, wherein each of the said samples are separated in time.

Abstract
A receiver which comprises means for receiving a first plurality of signals at different frequencies at the same time, means for generating a second plurality of signals (116), a mixer (114) for receiving, at the same time, the first plurality of signals at different frequencies and one of the second plurality of signals at a time wherein the second plurality of signals are mixed by the mixer (114) in succession, said first plurality of signals being mixed with successive ones of the second plurality of signals and filter means (320) for mixing signals output from said mixer (114), said filter means (120) being arranged to provide a series of samples of the first plurality of signals at the same frequency, wherein each of the said samples are separated in time.

15. A method of receiving comprising the steps of:
-
receiving a first plurality of signals at different frequencies;
generating a second plurality of signals;
reducing the frequency of the first plurality of signals by mixing the first plurality of signals at different frequencies at the same time, and one of the second plurality of signals at a time wherein the second plurality of signals are received by the mixer in succession, said first plurality of signals being mixed with successive ones of the second plurality of signals;
providing a series of samples by filtering of the first plurality of signals at the same frequency, each of said samples being separated in time.
