Method for reducing sglte coupling de-sense and mobile terminal

A mobile terminal capable of SGLTE communications, comprising:

• a GSM signal transmission end coupled to a GSM transmission path for transmitting GSM signals;
• a GSM signal reception end coupled to a GSM reception path;
• a band stop filter deployed in the GSM transmission path to filter out an LTE frequency band in a signal to be transmitted in the GSM signal transmission end;
• and
• A GSM reception filter deployed in the reception path to filter out all frequency bands other than a GSM frequency band in a received signal on the GSM signal reception end.

A mobile terminal, comprising:

• a GSM signal transmission end coupled to a GSM transmission path for transmitting GSM signals;
• a GSM signal reception end coupled to a GSM reception path for receiving GSM signals;
• a band stop filter coupled to the GSM signal transmission end;
• a processor, adapted to execute instructions;
• and
• a memory, adapted to store instructions, wherein:
• the processor loads the instructions from the memory to perform the following steps:
• employing the band stop filter to filter out an LTE frequency band in a signal to be transmitted in the GSM signal transmission end while keeping a GSM transmission loss under 1 dB;
• and
• filtering out all frequency bands other than a GSM frequency band in a received signal on the GSM signal reception end.
