    • A transmitter encodes an input bitstream using space-time trellis coding (STTC). The encoder includes a serial to parallel convertor to produce a first and second output bitstreams. First and second three bit shift registers are connected to produce first and second output bitstreams. A multiplier applies a code generating weight to each bit of the shift registers to encode the bitstreams. A first switch is connected between a last bit of the first shift register and a first bit of the second shift register. A second switch is connected between the second output and the first bit of the second shift register. The first set of encoded bit streams and the second set of encoded bitstreams are combined and mapped to a frequency domain.

    • This invention provides method and device for blind transfer service. The method comprises the following steps: first, user A establishes a call with user B, then, user B originates a call transfer request to request to transfer the call with user A to user C; application server of user B heads off the request and returns an accept response to user B; the application server of user B firstly originates a call invitation to user C and acquires media parameter information of user C; the application server of user B originates a call re-invitation to user A, provides the media parameter information of user C, instructs user A to carry out media switch, and acquires media parameter information of user A; the application server of user B provides the media parameter information of user A to user C, and instructs user C to establish a media stream connection with user A.
    • 本发明提供了盲传服务的方法和装置。 该方法包括以下步骤:首先,用户A与用户B建立呼叫,用户B发起呼叫转移请求,请求用户A向用户C传送呼叫; 用户B的应用服务器退出请求,并向用户B返回接受响应; 用户B的应用服务器首先发起对用户C的呼叫邀请,并获取用户C的媒体参数信息; 用户B的应用服务器发起对用户A的呼叫重新请求,提供用户C的媒体参数信息,指示用户A执行媒体交换,并获取用户A的媒体参数信息; 用户B的应用服务器向用户C提供用户A的媒体参数信息,并指示用户C与用户A建立媒体流连接。
