| 摘要 |
A receiver (39) receives spread spectrum signals which also include unwanted narrowband signals, for example, radio signals which comprise a mixture of signals from signal sources using the Group Special Mobile (GSM) ETSI standard coding and from signal sources using Code Division Multiple access (CDMA) coding. The unwanted narrowband signals have been coded using a coding scheme with error correction capabilities. In the invention, the narrowband signal is decoded (42), regenerated (44) and subtracted (46) prior to despreading (21) of the spread spectrum signal. |
