| Abstract: | The paper studies the downlink of GGE and related single antenna interference cancellation (SAIC) technology.A LMS adaptive channel estimation algorithm is proposed to improve the performance of linear filtering and enhance the capability of interference cancellation.For suppressing the multicell asynchronous interference,an adaptive judgment mechanism is designed in LMS adaptive channel estimations to extend the applicative range of LMS and improve the performance of channel estimation in asynchronous multicell scenarios. |

| Keywords: | multicell asynchronous interference single antenna interference cancellation channel estimation |
